Pmic For Safety-Related Systems With Buc A81407KLVATR
The A81407 is ideal for both Automotive and Industrial applications, where high temperature operation, a high level of integration, and robust solutions are required. The IC integrates a buck or buck/boost pre-regulator, four linear and low-dropouts (LDO), and four floating gate drivers. The pre-regulator uses a buck or buck/boost topology to efficiently convert input voltages into a tightly regulated intermediate voltage. Frequency dithering and slew control help reduce EMI. The output of the pre-regulator supplies a 3.3 V / 375 mA linear regulator, a 5 V / 150 mA linear regulator, and two 5 V / 120 mA linear regulators. All of the outputs are protected against short circuits, and two are further protected from short-to-supply voltage in case they are used remotely. The independent floating gate drivers can be used for switched loads such as motor phases, solid state relays, and solenoid valves. They have the capability of controlling N-channel MOSFETs through SPI. An integrated charge pump allows the driver outputs to maintain the power MOSFETs in the on state over the full supply range with high phase-voltage slew rates. Diagnostic outputs from the A81407 include a Watchdog Fault (WD_Fn), power-on reset (NPOR), and a fault flag (FFn) to alert the microprocessor that a fault has occurred. The microprocessor can read fault registers through SPI and operational status via an analog multiplexor.
