3 Description
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).
