STM1061

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 V

input and compares it with a specified voltage threshold condition. When V

falls below a

specified trip point threshold, the output (OUT) is forced low and remains asserted as long

as the V

input remains below V

TH–

+ hysteresis (V

HYST

). The STM1061 device is

guaranteed to output the correct logic state for V

down to 0.7V. They are also designed to

ignore fast transients on V

This small, low power device is ideal for portable applications and is available in space-

saving SOT23-3 and SOT323-3 (SC70-3) packages.
