AMS23M1 Description
The AMS23 low power voltage detector provides monitoring of battery, power-supply, and regulated system voltages. A precision voltage reference and parator monitors the VCC input and pares it with a specified voltage threshold condition. When VCC falls below a specified trip point threshold, the output (OUT) is forced low and remains asserted as long as the VCC input remains below VTH- + hysteresis (VHYST).
