ASM1811 - Alliance Semiconductor

ASM1811 Low Power 5V uP Reset Active LOW

The ASM1811 is a voltage supervisory device with a low-power, 5V µP Reset, active LOW, open-drain output. Maximum supply current over temperature is a low 20µA. The ASM1811 generates an active LOW reset signal whenever the monitored supply is out of tolerance. A precision reference and comparator circuit monitor power supply (VCC) level. Tolerance level opti.
