STM1061：Low power voltage detector

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