Summary Description

The STM1061 low power voltage detector provides monitoring of battery, power-supply, and

regulated system voltages. A precision voltage reference and 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 STM1061 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 SOT23-3 and SOT323-3 (SC70-3) packages.
