Texas Instruments DRV8962-Q1 Four-Channel Half-Bridge Driver

Texas Instruments DRV8962-Q1 Four-Channel Half-Bridge Driver is a wide-voltage, high-power, four-channel half-bridge driver for various automotive applications. The device supports up to 60V supply voltage, and integrated MOSFETs with 50mΩ on-resistance allow up to 5A current on each output. The device can drive up to one stepper motor, four solenoids or valves, one BLDC or PMSM motor, two brushed-DC motors, and two thermoelectric coolers (Peltier elements). The output stage consists of N-channel power MOSFETs configured as four independent half-bridges, a charge pump, regulation circuits, current sensing, protection circuitry, and current sense outputs.

With integrated current sensing across the high-side MOSFETs, the device can regulate the current when the load is connected from output to ground. This regulated current limit can be set with an adjustable external voltage reference (VREF). The device provides four proportional current output pins, one for each half-bridge high-side FET. Optional external sense resistors can also be connected from the PGND pins to the system ground. A low-power sleep mode achieves ultra-low quiescent current. The Texas Instruments DRV8962-Q1 provides internal protection features for supply undervoltage lockout, output over current, and device overtemperature.
