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.

! 3 Output Types: Push/Pull RESET, Push Pull RESETN, and Open Drain RESETN Reset Threshold Range: 1.6 to 2.5V (~100mV increments) RESET/RESETN: - Valid to VCC = 0.7V (AS1907 and AS1908) - Valid to VCC = 1.0V (AS1909) Reset Pulse Widths: 1, 20, and 100ms Supply Voltage Range: +0.7 to +3.6V Supply Current Range: 2.6 to 7.0µA Power Supply Transient Immunity Requires No External Components Operating Temperature Range: -40 to +125ºC 3-pin SOT23 Package ! ! ! ! ! ! ! ! The reset thresholds are fa.
