The ASM1811 is a low-power, 5V µP Reset, active LOW, open-drain output voltage supervisory device.
The ASM1811 is a voltage supervisory device designed to generate an active LOW reset signal when the monitored supply voltage is out of tolerance. It features a precision reference and comparator circuit to monitor the Vcc level, ensuring system stability during power-up and power-down transitions.
