A4810A - ULTRA-LOW VOLTAGE DETECTOR

Datasheet Summary

Features

  • The A4810A/B microprocessor supervisory circuit can be used to monitor the power supplies in microprocessor and digital systems. It provides a reset to the microprocessor during power-up, power-down, and brown-out conditions.
  • The function of the A4810A/B is to monitor the VDD supply voltage, and assert a reset signal whenever this voltage declines below the factory-programmed reset threshold. The reset signal remains asserted for 250ms after VDD rises above the threshold. The A481.

AiT Semiconductor Inc. www.ait-ic.com A4810A/B HIGH PRECISION BUILT-IN DELAY CIRCUIT FULL TEMP RANGE, ULTRA-LOW VOLTAGE DETECTOR DESCRIPTION FEATURES The A4810A/B microprocessor supervisory circuit can be used to monitor the power supplies in microprocessor and digital systems. It provides a reset to the microprocessor during power-up, power-down, and brown-out conditions.   The function of the A4810A/B is to monitor the VDD supply voltage, and assert a reset signal whenever this voltage declines below the factory-programmed reset threshold. The reset signal remains asserted for 250ms after VDD rises above the threshold. The A4810A/B has an active-low /RESET output.      Precise monitoring of 2.7V, 3.0V, 3.3V and 5.0V supplies 140 ms min.
