It combines a 1.7A\/2.3A gate driver for six external N-channel MOSFETs, a built-in 1.5A buck regulator for MCU power, and two current sense amplifiers with programmable gain (10-80V\/V). The 6V-60V supply range covers automotive and industrial motor systems, while the SPI interface provides full configuration control and detailed fault reporting. The HTSSOP-28 PowerPAD package ensures efficient thermal management.","working_principle":"The DRV8301DCAR consists of three main subsystems: (1) Gate Driver \u2014 three half-bridge gate drivers with adaptive dead-time and charge-pump boosted gate drive for 100% duty cycle operation. Each driver provides 1.7A source \/ 2.3A sink peak current to rapidly charge\/discharge external MOSFET gates. (2) Buck Regulator \u2014 a synchronous step-down converter that generates 5V or 3.3V at 1.5A from the motor supply voltage, powering the MCU and external logic without a separate voltage regulator. (3) Current Sense Amplifiers \u2014 two differential amplifiers that measure the voltage across external low-side shunt resistors, with programmable gains of 10, 20, 40, or 80 V\/V. The SPI interface allows reading fault registers and adjusting gate drive strength, dead time, and CSA gain.","pin_description":"
