ASM1816 - Alliance Semiconductor

ASM1816 Low Power 3.3V/3.0V uP Reset

The ASM1816 is a voltage supervisory device with low-power, 3.3V/3V µP Reset, active LOW, open-drain output. Maximum supply current over temperature is a low 15µA (at 3.6V). The ASM1816 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. Toleran.
