ASM1812 - Alliance Semiconductor

ASM1812 Low Power 5V uP Reset Active HIGH

The ASM1812 is a voltage supervisory device with low-power, 5V µP Reset, active HIGH, Push-Pull output. Maximum supply current over temperature is a low 20µA. The ASM1812 issues an active HIGH reset signal whenever the monitored supply is out of tolerance. A precision reference and comparator circuit monitor power supply (VCC) level.
