Description

The NCP81005 is a cost-effective system supervisor circuit that monitors the VCC in digital systems and sends a reset signal to the host processor when necessary. This electronic component belongs to the special purpose voltage regulators category, and it's optimized to reject fast transient glitches on the VCC line. It's suitable for battery-powered applications since its supply current is low, only 0.5 μA when VCC equals 3.2 V.
