Timers and RTCs
Timers and Real-Time Clocks (RTCs) are electronic devices that are used to measure time or keep track of the current time. They can be found in a wide range of applications, including computers, phones, and appliances. Timers are used to trigger an action after a specific period of time has elapsed. They can be used to control the duration of an event, or to schedule tasks to be performed at a later time. RTCs, on the other hand, are used to maintain accurate time even when the device is powered off. They are often used in devices that need to keep track of the current time and date, such as alarm clocks and smart thermostats. If you're looking for high-quality timers and RTCs for your electronic projects, you should check out Flux.ai.

TLC555IP
555 Type, Timer/Oscillator (Single) IC 2.1MHz 8-PDIP The TLC555 is a CMOS monolithic timing circuit. The timer is fully compatible with CMOS, TTL, and MOS logic and operates at frequencies up to 2MHz. Because of a high input impedance, this device supports smaller timing capacitors than those supported by the NE555 or LM555. As a result, more accurate time delays and oscillations are possible. Power consumption is low across the full range of power-supply voltage. • Very low power consumption: – 1mW typical at VDD = 5V • Capable of operation in astable mode • CMOS output capable of swinging rail to rail • High output current capability – Sink: 100mA typical – Source: 10mA typical • Output fully compatible with CMOS, TTL, and MOS • Low supply current reduces spikes during output transitions • Single-supply operation from 2V to 15V • Functionally interchangeable with the NE555; has same pinout • ESD protection exceeds 1000V per ANSI/ESDA/ JEDEC JS-001 • Available in Q-temp automotive – High-reliability automotive applications – Configuration control and print support – Qualification to automotive standards #CommonPartsLibrary #IntegratedCircuit

555 Type, Timer/Oscillator (Single) IC 2.1MHz 8-PDIP Like the NE555, the TLC555 has a trigger level equal to approximately one-third of the supply voltage and a threshold level equal to approximately two-thirds of the supply voltage. These levels can be altered by use of the control voltage terminal (CONT). When the trigger input (TRIG) falls below the trigger level, the flip-flop is set and the output goes high. If TRIG is above the trigger level and the threshold input (THRES) is above the threshold level, the flip-flop is reset and the output is low. The reset input (RESET) can override all other inputs and can be used to initiate a new timing cycle. If RESET is low, the flip-flop is reset and the output is low. Whenever the output is low, a low-impedance path is provided between the discharge terminal (DISCH) and GND. All unused inputs must be tied to an appropriate logic level to prevent false triggering. • Very low power consumption: – 1mW typical at VDD = 5V • Capable of operation in astable mode • CMOS output capable of swinging rail to rail • High output current capability – Sink: 100mA typical – Source: 10mA typical • Output fully compatible with CMOS, TTL, and MOS • Low supply current reduces spikes during output transitions • Single-supply operation from 2V to 15V • Functionally interchangeable with the NE555; has same pinout • ESD protection exceeds 1000V per ANSI/ESDA/ JEDEC JS-001 • Available in Q-temp automotive – High-reliability automotive applications – Configuration control and print support – Qualification to automotive standards #CommonPartsLibrary #IntegratedCircuit
347 Uses0 StarsTPS3828-33DBVR
Supervisor Open Drain or Open Collector 1 Channel SOT-23-5 The TPS382x family of supervisors provide circuit initialization and timing supervision, primarily for DSP and processor-based systems. During power on, RESET asserts when the supply voltage VDD becomes greater than 1.1V. Thereafter, the supply voltage supervisor monitors VDD and keeps RESET active low as long as VDD remains less than the threshold voltage, VIT−. An internal timer delays the return of the output to the inactive state (high) to make sure proper system reset. The delay time, td, starts after VDD has risen above the threshold voltage (VIT− + VHYS). When the supply voltage drops below the threshold voltage VIT−, the output becomes active (low) again. No external components are required. All the devices of this family have a fixed-sense threshold voltage, VIT–, set by an internal voltage divider. The TPS382x family also offers watchdog time out options of 200ms (TPS3820) and 1.6s (TPS3823, TPS3824, and TPS3828). • Power-on reset generator with a fixed delay time of 200ms (TPS3823, TPS3824, TPS3825, and TPS3828) or 25ms (TPS3820) • Manual reset input (TPS3820, TPS3823, TPS3825, and TPS3828) • Reset output available in active-low (TPS3820, TPS3823, TPS3824, and TPS3825), active-high (TPS3824 and TPS3825), and open drain (TPS3828) • Supply voltage supervision range: 2.5V, 3V, 3.3V, 5V • Watchdog timer (TPS3820, TPS3823, TPS3824, and TPS3828) • Supply current of 15μA (typical) • 5-pin SOT-23 package • Temperature range: −40°C to 85°C (−40°C to 125°C for TPS3823A-33) #CommonPartsLibrary #IntegratedCircuit #PowerManagement #Supervisor
