Texas Instruments Relays - Signal Relays, Up to 2 Amps TPS3840PL28DBVRQ1

The TPS3840PL28DBVRQ1 is an automotive-grade voltage supervisor with an active-low push-pull reset output, designed for monitoring power supply voltages in automotive systems. It operates from 1.5V to 10V with a typical quiescent current of 350nA and is packaged in a 5-pin SOT-23 measuring 2.90mm by 1.60mm. The device has a fixed reset threshold of 2.8V with 1% typical accuracy and includes built-in hysteresis. Reset delay is programmable via an external capacitor, ranging from 50µs with no capacitor to 6.2s with a 10µF capacitor. It is AEC-Q100 qualified for temperature grade 1 (-40°C to +125°C), with HBM ESD classification level 2 and CDM classification level C7B. Pullup resistors and external circuitry extend its input voltage range.
