DUAL H-BRIDGE MOTOR DRIVER
- DESCRIPTION
The UMD9148 provides a dual H-bridge motor driver for home appliances and other mechatronic applications. 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 inter facing 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 UMD9148 is capable of driving up to 2A of...
