AS1903 Product details

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.
