Texas Instruments DRV8962 65V 4-Channel Half-Bridge Driver

Texas Instruments DRV8962 65V 4-Channel Half-Bridge Driver is a wide-voltage, high-power, four-channel half-bridge driver for various industrial applications. The device supports up to 65V supply voltage, and integrated MOSFETs with 50mΩ on-resistance allow up to 5A current on each output with the DDW package; and up to 10A current per output with the DDV package.

The Texas Instruments DRV8962 can drive up to four solenoids or valves, one stepper motor, two brushed-DC motors, one BLDC or PMSM motor, and up to two thermoelectric coolers (Peltier elements). The output stage of the device consists of N-channel power MOSFETs configured as four independent half-bridges, a charge pump regulator, current sensing and regulation circuits, current sense outputs, and protection circuitry.

Integrated current sensing across the high-side MOSFETs allows the device to regulate the current when the load is connected from output to ground. An adjustable external voltage reference (VREF) can set a current regulation limit. Additionally, the device provides four proportional current output pins, one for each half-bridge high-side FET. Optional external sense resistors can be connected from the PGND pins to the system ground.

A low-power sleep mode is provided to achieve ultra-low quiescent current. Internal protection features are provided for supply undervoltage lockout (UVLO), charge pump undervoltage (CPUV), output over current (OCP), and device overtemperature (OTSD).
