A current mirror approximates the current through the high-side FETs, and does not require a sense resistor. A low-power sleep mode is provided to achieve very low quiescent current draw by shutting down much of the internal circuitry.
Internal protection functions are provided for undervoltage lockout, charge pump faults, overcurrent protection, short circuit protection, and overtemperature with fault conditions indicated on an nFAULT pin and through the SPI registers.
