AS1907 Datasheet (austriamicrosystems AG) - Low-Voltage Microprocessor Reset Circuits

AS1907, Low-Voltage Microprocessor Reset Circuits

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
