The DRV8952 is a wide-voltage, high-power, four-channel half-bridge driver for a wide variety of industrial applications. The device supports up to 55V supply voltage, and integrated MOSFETs with close to 50mΩ on-resistance allow up to 5A current on each output with the DDW package; and up to 4A current per output with the PWP package.
The device can be used for driving 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, 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. A current regulation limit can be set with an adjustable external voltage reference (VREF). With the DDW package, 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).
