ASM1816 - Low Power 3.3V/3.0V uP Reset

General Description

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.

Key Features

  • Low Supply Current.
  • 20 µA maximum (5.5 V).
  • 15µA maximum (3.6 V).
  • Automatically restarts a microprocessor after power failure 150ms reset delay after VCC returns to an in-tolerance condition Active LOW power-up reset Precision temperature-compensated voltage reference and comparator Eliminates external components TO-92 and compact surface mount SOT-23 package Operating temperature -40°C to +85°C Block.
