ASM8500 - Low Power 5V / 3.3V uP Reset Active

Description

The ASM8500 is a voltage supervisory device with a low-power, 5V/3.3V µP Reset, active LOW, open-drain output.

Maximum supply current over temperature is a low 6µA.

The ASM8500 generates an active LOW reset signal whenever the monitored supply is out of tolerance.

Features

  • Low Supply Current.
  • 6 µA maximum (5.5 V) Automatically restarts a microprocessor after power failure 1.5ms 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 Compact surface mount SOT-89 package Operating temperature -40°C to +85°C Supply Tolerance Bias ASM8500 5ΚΩ RESET +.

November 2003 rev 1.0 ASM8500 Low Power 5V / 3.3V µP Reset Active LOW, Open - Drain Output • • Printers Single board computers General Description The ASM8500 is a voltage supervisory device with a low-power, 5V/3.3V µP Reset, active LOW, open-drain output. Maximum supply current over temperature is a low 6µA. The ASM8500 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. Reset threshold tolerance level is ±1.5%. When an out-of-tolerance condition is detected, an internal power-fail signal is generated which forces an active LOW reset signal. After VCC returns to an in-tolerance condition, the reset signal remains active for www.DataSheet4U.com 1.
