... STM1061 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 input and compares it with a specified voltage threshold condition. When V specified trip point threshold, the output (OUT) is forced low and remains asserted as long ...

... Voltage Detect Release (V CC valid down The STM1061has an open drain active-low output which will sink current when output is asserted. Connect a pull-up resistor from OUT to any supply voltage (see on page 6). Select a resistor value large enough to register a logic low, and small enough to register a logic high while all of the input current and leakage paths connected to the reset output line are being supplied ...
