ASM1233M Datasheet Voltage Supervisors

Manufacturer: Alliance Semiconductor

Overview: .. October 2003 rev 1.0 ASM1233M Low Power, 5V/3.0V, µP Reset, Active LOW, Open-Drain Output Applications • • • • • • • Set-top boxes Cellular phones PDAs Energy management systems Embedded control systems Printers.

General Description

The ASM1233M is a voltage supervisor with low-power, 5V µP Reset, with an active LOW, open-drain output.

Maximum supply current over temperature is a low 20µA.

The ASM1233M 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 350ms reset delay after VCC returns to an in-tolerance condition Active LOW power-up reset, 5kΩ internal pull-up Precision temperature-compensated voltage reference and comparator Eliminates external components Low-cost TO-92 package Compact surface mount SO-8 package O.
