Reset timeout and output drive
The reset timeout is a minimum of 100ms, which gives the monitored supply rail time to stabilize before the system is released from reset. The open-drain output allows the reset line to be wire-ORed with other reset sources — common in multi-supply boards where a power-good signal from a PMIC or another supervisor needs to share the same reset bus. Pull-up resistor selection is the only external component needed; the output sinks current to ground when asserted.
Housed in a SOT-23-6 package, this part is surface-mount. The six-pin layout keeps routing simple: two sense inputs, ground, reset output, and supply.
