GENERAL DESCRIPTION

The AD5100 is a programmable system-management IC that combines 4-channel of voltage monitoring and a watchdog supervision that can be used to shutdown external supplies, reset processors, or disable any other system electronics when the systems malfunction. The AD5100 can also be used to protect system under faulty condition of improper devices power up sequencing. The AD5100 can monitor two 30V inputs with shutdown and reset controls, one 2.5V-5.0V and one 0.9V-3.3V monitoring inputs with reset control, a robust watchdog reset controller. Most monitoring input thresholds and timing settings can be programmed on the fly or permanently set in the factory with the OTP feature.
