The DRV8844 provides four individually controllable 1/2-H-bridge drivers. The device 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 2.5A peak or 1.75A RMS output current per channel (with proper PCB heatsinking at 24V 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.
Internal shutdown functions are provided for over current protection, short circuit protection, undervoltage lockout, and overtemperature.
The DRV8844 is available in a 28-pin HTSSOP package with PowerPAD™ (Eco-friendly: RoHS & no Sb/Br).
