ASM1812 - Low Power 5V uP Reset Active HIGH

General Description

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.

Key Features

  • Low Supply Current.
  • 20 µA maximum (5.5 V) Automatically restarts a microprocessor after power failure 150ms reset delay after VCC returns to an in-tolerance condition Active HIGH power-up reset Precision temperature-compensated voltage reference and comparator Eliminates external components TO-92 and compact surface mount SOT-23 package Push-Pull output for minimum current drain Operating temperatur.

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. Tolerance level options are 5%, 10% and 15%. When an out-oftolerance condition is detected, an internal power-fail signal is generated which forces an active HIGH reset signal.
