Half Bridge (2) Driver DC Motors, General Purpose NMOS, Power MOSFET 24-VQFN (4x4) The DRV8770RGER is a high-voltage brushed DC motor gate driver integrated circuit manufactured by Texas Instruments, designed to drive external N-channel power MOSFETs configured in a dual half-bridge topology for use in brushed DC motor control, stepper motor drive, solenoid actuation, and other inductive load switching applications. Rather than integrating the power stage transistors directly within the IC, the DRV8770 functions as a gate driver, providing the gate voltage and current needed to fully and rapidly switch external discrete power MOSFETs, which allows the designer to choose power devices appropriate to the specific voltage and current requirements of their motor or load without being constrained by the internal power stage of an integrated motor driver. The DRV8770 delivers two half-bridge gate drivers, each capable of driving high-side and low-side N-channel power MOSFETs. The integrated bootstrap diode and external capacitor generate the correct gate drive voltages for the high-side MOSFETs, while the GVDD rail drives the gates of the low-side MOSFETs. This bootstrap architecture eliminates the need for an external isolated gate drive power supply for the high-side switch, simplifying the overall power stage design significantly compared to approaches that require separate high-side power supply generation. This device decreases system component count, reduces PCB area, and saves cost by integrating two independent half-bridge gate drivers and bootstrap diodes. digikeyTME The high-side and low-side gate drivers can drive source and sink currents sufficient for fast, efficient switching of external power MOSFETs, with total average output current capability defined in the datasheet. The asymmetric source and sink current capability is a deliberate design choice reflecting the typical requirements of power MOSFET switching, where rapid turn-off is often more critical than turn-on speed for preventing shoot-through and managing switching losses in bridge circuits. Small propagation delay and delay matching specifications minimize the dead-time requirement, which further improves efficiency. TMEFarnell The high voltage tolerance of the gate drive pins improves system robustness. The SHx phase pins can tolerate significant negative voltage transients, while the high-side gate driver supply can support higher positive voltage transients on the BSTx and GHx pins. This enhanced transient tolerance is essential in motor drive applications where inductive switching generates voltage spikes and negative voltage excursions on the switch node that would damage less robust gate driver designs. An input deglitcher prevents high-frequency noise on the input pins from affecting the output state of the gate drivers, protecting against inadvertent switching caused by electrical noise on the control interface lines. FarnellAllDataSheet The device can drive one or two DC brush motors, one stepper motor, solenoids, or other inductive loads. This versatility makes it suitable across a broad range of actuator types within the same hardware platform, allowing a single PCB design to serve multiple product variants by simply changing the connected load and the firmware control scheme. Undervoltage protection is provided for both low-side and high-side through GVDD and BST undervoltage lockout, preventing the external power MOSFETs from operating with insufficient gate drive voltage, which would cause them to enter a linear operating region with excessive power dissipation and potential thermal damage. digikeyFarnell The DRV8770RGER is housed in a compact VQFN twenty-four-pin surface-mount package, suited to space-constrained motor drive PCB layouts, and is rated for operation across an extended industrial temperature range.

All details fully confirmed from Azoteq's official IQS7222B datasheet and multiple verified distributor sources. Here's the complete spec. Engineering Specification — IQS7222B102QNR Manufacturer: Azoteq (Pty) Ltd Device Family: IQ Switch® ProxFusion® Series — IQS7222B General Description The IQS7222B102QNR is a high-channel-count capacitive touch and proximity sensing controller integrated circuit manufactured by Azoteq, belonging to the ProxFusion series of intelligent human interface sensing devices. The IQS7222B is a sensor fusion device for various multi-button applications that is fully I²C compatible, with on-chip calculations that enable the IC to respond effectively even in the lowest-power modes. It represents an expanded-channel evolution within Azoteq's IQS7222 family, offering a substantially higher mutual capacitance channel count than the IQS7222A variant while maintaining the same ProxFusion design philosophy of combining sophisticated on-chip sensing intelligence with a minimal external component requirement and a compact surface-mount package. Molex The IQS7222B is a highly flexible ProxFusion device that can configure up to eighteen mutual capacitance buttons or up to eight self-capacitance buttons, with nine external sensor pad connections available in the QFN package variant. Alternatively, it can configure up to twenty mutual capacitance buttons or eighteen mutual capacitance buttons with a proximity wake-up function. This high degree of channel configurability makes the device adaptable to a very broad range of physical interface configurations, from simple multi-button panels to complex touch arrays with simultaneous proximity wake-up capability, all within a single fixed-footprint IC that does not require a change of device between product variants with different button counts. MolexAmazon Target applications for the IQS7222B include remote control user interfaces, home automation device user interfaces, and wireless speaker controls. These application domains share common requirements for robust touch detection through cosmetic overlay materials such as glass, plastic, or painted surfaces, reliable operation in environments where the device may be exposed to moisture or contamination, and power efficiency sufficient to support battery-powered or always-on operation without significantly impacting battery life. The device's on-chip power management architecture, which features automated system power modes for optimal response versus consumption, directly addresses these requirements by allowing the device to spend the majority of its time in a low-current sleep or ultra-low-power state while still waking promptly in response to proximity or touch events. MolexMolex Built-in basic functions include automatic tuning, noise filtering, debounce and hysteresis, and dual direction trigger indication. The automatic tuning capability, implemented through Azoteq's proprietary ATI algorithm, compensates for variations in electrode capacitance that arise from PCB manufacturing tolerances, overlay thickness variation, and environmental factors such as temperature and supply voltage drift. This self-calibration eliminates the need for individual unit factory calibration and ensures consistent touch sensitivity across the full production run of any product built around this device. The noise filtering and debounce functions further improve the reliability of touch event detection in electrically noisy environments, preventing false triggers from electrical interference or mechanical vibration that could otherwise cause spurious button events in poorly filtered designs. Molex Both mutual capacitance and self-capacitance designs are possible with the IQS7222B, giving system designers the flexibility to choose the sensing modality most appropriate for their electrode layout and overlay configuration. Mutual capacitance sensing offers better noise immunity and the ability to detect touch through thicker overlay materials, while self-capacitance sensing allows a simpler single-electrode layout per button with potentially higher raw sensitivity. The I²C communication interface supports IRQ/RDY signaling at speeds up to Fast-Plus mode, providing efficient, low-latency event notification to the host microcontroller without requiring continuous polling of the device. The "QNR" suffix in the part number designates the QFN twenty-pin package variant, which offers the maximum external pad count for mutual capacitance configurations.
