Description
General part information
DRV8844 Series
The DRV8844 provides four individually controllable 1/2-H-bridge drivers. It can be used to drive two DC motors, one stepper motor, four solenoids, or other loads. The output driver channel for each channel consists of N-channel power MOSFET’s configured in a 1/2-H-bridge configuration.
The DRV8844 can supply up to 2.5-A peak or 1.75-A RMS output current per channel (with proper PCB heatsinking at 24 V and 25°C) per H-bridge.
Separate inputs to independently control each 1/2-H-bridge are provided. To allow operation with split supplies, the logic inputs and nFAULT output are referenced to a separate floating ground pin.
