The pre-regulator uses a buck or buck\/boost topology to efficiently convert the voltage of an automotive battery to a precisely regulated intermediate voltage, and provides control, diagnostic and protection functions. \u003c\/p\u003e\n\u003cp\u003eThe output of the front-end regulator provides a selectable 3.3 V or 5.0 V 350 mA linear regulator, a 5 V \/ 115 mA linear regulator, and two 120 mA protected linear regulators for tracking the VUC output. The ARG82801 is designed to power microprocessors, sensors, and CAN transceivers, making it highly suitable for engine compartment applications. \u003c\/p\u003e\n\u003cp\u003eThe independent floating gate driver can control N-channel MOSFETs via SPI. These MOSFETs can be configured as phase or battery isolation devices in high-current motor applications. The integrated charge pump enables the driver to output and maintain the power MOSFETs in the on-state throughout the entire power supply range with a high phase-voltage conversion rate. The inputs to the ARG82801 include logic level (ENB) and high voltage (ENBAT). The ARG82801 also provides flexible individual output power disable functions through the Serial Peripheral Interface (SPI). \u003c\/p\u003e\n\u003cp\u003eThe diagnostic output of the ARG82801 includes power-on reset output (NPOR) and fault flag output (FFn) to alert the faulty microprocessor. The microprocessor can read the fault status via SPI. The dual air gap enhances the safety coverage and fault detection of the ARG82801, one for voltage regulation and the other for fault checking. \u003c\/p\u003e\n\u003cp\u003eThe ARG82801 includes two types of watchdog functions: question-and-answer and window watchdog. The watchdog timer is activated after receiving a valid SPI command from the processor. The watchdog can enter flash mode or be reset via SPI commands. \u003c\/p\u003e\n\u003cp\u003eThe ARG82801 is available in a low-profile 38-lead eTSSOP package (suffix \"LV\") with a maximum height of 1.2 mm and features an exposed thermal pad.
