Description

The IMP690ACSA is an electronic component model in the IC Chips category. It simplifies power supply monitoring and control in microprocessor systems. It implements four functions: reset control, watchdog monitoring, battery backup switching, and power-failure monitoring. This model provides microprocessor reset under power-up and power-down conditions, as well as battery-backup switching to maintain control in power loss and brown-out situations. It also offers additional monitoring capabilities to provide an early warning of unregulated power-supply loss.
