Low-Voltage UP Supervisory Circuit, Active-Low Push/Pull Reset

The AS1907 AS1908 AS1909 Microprocessor Supervisory Circuits are ideal for monitoring the supply voltage of digital systems and Microprocessors
The devices are designed to initiate a reset if the supply voltage goes below a predefined threshold. The duration of the reset is either 1.5, 30, or 150ms (typ.) after the supply voltage has risen above the pre-set threshold.
