Texas Instruments DRV8421 Dual H-Bridge Motor Driver is ideal for home appliances and other mechatronic applications. The device can drive a bipolar stepper motor, one or two DC motors, or other loads. A PWM interface allows easy interfacing with controller circuits. The output block of each H-bridge driver consists of N-channel power MOSFETs configured as full H-bridges to drive the motor windings. The DRV8421 can drive a maximum current of 2A from each output or 4A in parallel mode (with proper heat sinking at 12V and TA = 25°C).
