Notice: The information in this document is subject to change without notice rev 1.3 Low Power, 5V/3.3V, µP Reset, Active LOW, Open-Drain Output March 2005 General Description The ASM1233D-L/1233D/1233M are voltage supervisors with low-power, 5/3.3V µP Reset, with an active LOW, open-drain output. Maximum supply current over temperature is 15µA for 3.3V devices and 20µA for 5V devices. The ASM1233D-L/1233D/1233M generates an active LOW reset signal whenever the monitored supply is out of tolerance. A precision reference and comparator circuit monitors power supply (V CC) level. The tolerance are 5%,10% and 15%. 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 350ms to allow the power supply and system microprocessor to stabilize. The ASM1233D-L/1233D/1233M is designed with an open- drain output stage and operates over the extended industrial temperature range. These device s are available in compact SOT-223, SO-8 and TO-92 packages. Other low power products in this family include ASM1810/11/ 12/15/16/17. Key Features

  • Low Supply Current
  • 15µA maximum (<=3.6V), 20µA maximum (5.5V)
  • Automatically restarts a microprocessor after power failure
  • 350ms reset delay after V CC returns to an in-tolerance con- dition
  • Active LOW power-up reset, 5k Ω internal pull-up
  • Precision temperature-compensated voltage reference and comparator
  • Eliminates external components
  • Low-cost SOT-223/SO-8/TO-92 packages
  • Operating temperature: -40°C to +85°C
