The CS5111 is a dual output power management integrated circuit that includes a 5V ±2%, 100mA linear regulator, a watchdog timer, a linear output voltage monitor to provide a Power On Reset (POR) and a 1.4A current mode PWM switching regulator. The 5V linear regulator is comprised of an error amplifier, reference, and supervisory functions. It has low internal supply current consumption and provides 1.2V (typical) dropout voltage at maximum load current. The watchdog timer circuitry monitors an input signal (WDI) from the microprocessor. It responds to the falling edge of the WDI signal and restarts the device within 250ms. The CS5111 has a 54V peak transient capability to protect the load during a power failure.
