GENERAL DESCRIPTION
The AMS23 low power voltage detector provides monitoring of battery, power-supply, and regulated system voltages. A
precision voltage reference and comparator monitors the V_CC input and compares it with a specified voltage threshold
condition. When V_CC falls below a specified trip point threshold, the output (OUT) is forced low and remains asserted as long
as the V_CC input remains below V_TH- + hysteresis (V_HYST). The AMS23 device is guaranteed to output the correct logic state for
V_CC down to 0.7V. They are also designed to ignore fast transients on V_CC. This small, low power device is ideal for portable
applications and is available in space-saving SOT23-5 package.
