The ARG81401 is a power management IC that uses a buck or buck-boost pre-regulator to efficiently convert automotive battery voltages into a tightly regulated intermediate voltage, complete with control, diagnostics, and protections. The output of the pre-regulator supplies a 5V, 300mALDO and a 3.3V, 200 mALDO. Designed to supply CAN or microprocessor power supplies in high-temperature environments, the ARG81401 is ideal for underhood applications. Enable-input to the ARG81401 is compatible to a high-voltage battery level (ENBAT). Diagnostic outputs from the ARG81401 include a power-on-reset output (NPOR) with a fixed 22.5 ms typical delay. Dual bandgaps, one for regulation and one for fault checking, improve long-term reliability of a system designed around the ARG81401. The ARG81401 contains a window watchdog timer that can be programmed to accept a wide range of clock frequencies (WDADJ). The watchdog timer has a fixed 30 ms activation delay to accommodate processor startup. The watchdog timer has an enable/disable pin (active low, WDENn) to facilitate initial factory programming or field reflash programming. Protection features include dual control loop for pre-regulator rail. In case of a shorted output, all linear regulators feature foldback overcurrent protection. The switching regulator includes pulse-by-pulse current limit, hiccup mode short-circuit protection, LX short-circuit protection, missing asynchronous diode protection, and thermal shutdown. The ARG81401 is supplied in a low-profile (1.2 mm maximum height), 20-lead eTSSOP package (suffix “LP”) with exposed thermal pad.
