The TLV803EA18DPWR: This is a simple reset/power-on reset supervisor monitoring a single voltage rail. The open-drain output allows the reset signal to be wire-ORed with other supervisors or pulled up to a different logic voltage via an external resistor, matching the downstream processor's I/O level.
The voltage threshold is 1.8V, and the reset timeout is 130ms minimum. The output is active-low, open-drain, so it asserts low when the supply drops below 1.8V and releases after the timeout when the rail recovers.
