AS1902 - Ultra Low-Power uP Supervisory Circuit

Download the AS1902 datasheet PDF. This datasheet also covers the AS1901 variant, as both devices belong to the same ultra low-power up supervisory circuit family and are provided as variant models within a single manufacturer datasheet.

Description

The AS1901/2/3 family is an ultra low-power supervisory circuit device.

The device can be used to monitor the supply voltage of digital systems and microprocessors and initiate a reset when the voltage goes below a predefined threshold.

Features

  • ! ! Low 230nA (typ) Supply Current Precision Monitoring of 2.5-, 3-, and 3.3V-Power Supplies Supply Voltage Range: 1.0 to 3.6V Reset Threshold Range: 2.2 to 3.1V Available in 3 Versions: - AS1901 Push Pull RESETN - AS1902 Push Pull RESET - AS1903 Open Drain RESETN ! ! ! The AS1901 has a push-pull driver with an active low reset. The AS1902 uses the same output stage as the AS1901, but has an active high reset. The AS1903 has an open drain output with active low reset. ! ! ! ! 4 Time-Out Per.

The device can be used to monitor the supply voltage of digital systems and microprocessors and initiate a reset when the voltage goes below a predefined threshold. The duration of the reset is 5/20/100/500ms (typ.) after the supply voltage has risen above the threshold. The AS1901/2/3 exhibit excellent reliability and can reduce application costs by eliminating all external components. The device is available with different output drivers: ! 2 Key Features ! ! Low 230nA (typ) Supply Current Precision Monitoring of 2.5-, 3-, and 3.3V-Power Supplies Supply Voltage Range: 1.0 to 3.
