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. 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:

  • 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.

All devices operate down to a voltage of 1V.

The reset thresholds are factory-trimmable between 2.2V and 3.08V in steps of approximately 100mV.

Each device of AS1901/2/3 family is offered with four time-out periods of 5/20/100/500ms.

The extremely low current consumption of only 230nA (typ) at 3.3V makes the device ideal for use in portable applications.

All devices are available in a 3-pin SOT23 package.
