A precision voltage reference & comparator monitors the VCC input and compares 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). The AMS23 device is guaranteed to output the correct logic state for VCC down to 0.7V. They are also designed to ignore fast transients on VCC. This small, low power device is ideal for portable applications and is available in space-saving SOT23-5 package.
