STM1061 Summary Description
5/23
1 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
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 STM1061 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 SOT23-3 and SOT323-3 (SC70-3) packages.
