IC SURGE STOPPER 2.7V~18V WSON-8-EP(2x2) The TPS2595xx family of eFuses (integrated FET hot swap devices) is a highly integrated circuit protection and power management solution in a small package. The devices provide multiple protection modes using very few external components and are a robust defense against overloads, short circuits, voltage surges, and excessive inrush current. Output current limit level can be set with a single external resistor. It is also possible to get an accurate sense of the output load current by measuring the voltage drop across the current limit resistor. Applications with particular inrush current requirements can set the output slew rate with a single external capacitor. Overvoltage events are quickly limited by internal clamping circuits to a safe fixed maximum, with no external components required. The TPS259573 variant provides an option to set a user-defined overvoltage cutoff threshold. Quick output discharge function can be implemented in the TPS2595x5 variants by connecting the OUT pin to the QOD pin. The devices are characterized for operation over the temperature range of –40°C to +125°C. 1• Wide Input Voltage Range: 2.7 V to 18 V – 20 V Absolute Maximum – 3 V to 18 V for TPS2595x5 Version • Low On-Resistance: RON = 34 mΩ (Typical) • Fast Overvoltage Protection Clamp (3.8-V, 5.7-V, and 13.7-V options) With a Response Time of 5 µs (Typical) • TPS2595x0, TPS2595x1, TPS2595x5: Active High Enable Input With Adjustable Undervoltage Lockout (UVLO) • TPS2595x3: Active Low Enable Input With Adjustable Overvoltage Lockout (OVLO) • Adjustable Current Limit With Load Current Monitor Output (ILM) – Current Range: 0.5 A to 4 A – Current Limit Accuracy: ±7.5% • Adjustable Output Slew Rate Control (dVdt) • Over Temperature Protection (OTP) • Fault Indication Pin (FLT ) • UL 2367 Recognition – File No. E169910 – RILM >= 487 Ω (4.42 A maximum) • IEC 62368-1 Certified • Safe During Single Point Failure Test (IEC 62368- 1) – ILM Pin Open/Short Detection #CommonPartsLibrary #IntegratedCircuit #PowerManagement

Battery Battery Monitor IC Lithium Ion 8-TDFN-EP (2x2) The MAX17048/MAX17049 ICs are tiny, micropower current fuel gauges for lithium-ion (Li+) batteries in handheld and portable equipment. The MAX17048 operates with a single lithium cell and the MAX17049 with two lithium cells in series. The ICs use the sophisticated Li+ battery-modeling algorithm ModelGauge™ to track the battery relative state-ofcharge (SOC) continuously over widely varying charge and discharge conditions. The ModelGauge algorithm eliminates current-sense resistor and battery-learn cycles required in traditional fuel gauges. Temperature compensation is implemented using the system microcontroller. The ICs automatically detect when the battery enters a low-current state and enters low-power 3µA hibernate mode, while still providing accurate fuel gauging. The ICs automatically exit hibernate mode when the system returns to active state. On battery insertion, the ICs debounce initial voltage measurements to improve the initial SOC estimate, thus allowing them to be located on system side. SOC, voltage, and rate information is accessed using the I2C interface. The ICs are available in a tiny 0.9mm x 1.7mm, 8-bump wafer-level package (WLP), or a 2mm x 2mm, 8-pin TDFN package. ● MAX17048: 1 Cell, MAX17049: 2 Cells ● Precision ±7.5mV/Cell Voltage Measurement ● ModelGauge Algorithm • Provides Accurate State-of-Charge • Compensates for Temperature/Load Variation • Does Not Accumulate Errors, Unlike Coulomb Counters • Eliminates Learning • Eliminates Current-Sense Resistor ● Ultra-Low Quiescent Current • 3μA Hibernate, 23μA Active • Fuel Gauges in Hibernate Mode • Automatically Enters and Exits Hibernate Mode ● Reports Charge and Discharge Rate ● Battery-Insertion Debounce • Best of 16 Samples to Estimate Initial SOC ● Programmable Reset for Battery Swap • 2.28V to 3.48V Range ● Configurable Alert Indicator • Low SOC • 1% Change in SOC • Battery Undervoltage/Overvoltage • VRESET Alert ● I2C Interface ● 8-Bit OTP ID Register (Contact Factory) #CommonPartsLibrary #IntegratedCircuit #PowerManagement #Battery-management #MAX17048
