The device can be used to drive one or two DC motors, a bipolar stepper motor, or other loads. A simple PWM interface allows easy interfacing to controller circuits. The output block of each H-bridge driver consists of N-channel and P-channel power MOSFETs configured as full H-bridges to drive the motor windings. Each H-bridge includes circuitry to regulate the winding current using a fixed off-time chopping scheme. The DRV8848 is capable of driving up to 2 A of current from each output or 4 A of cu...
