The DRV8848 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 interfacing to controller
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 DRV8848 is capable of
driving up to 2 A of current from each output or 4 A of current in parallel mode (with proper heat
sinking, at 12 V and TA = 25°C).
A low-power sleep mode is provided, which shuts down internal circuitry to achieve
very-low quiescent current draw. This sleep mode can be set using a dedicated nSLEEP pin.
Internal protection functions are provided for UVLO, OCP, short-circuit protection, and
overtemperature. Fault conditions are indicated by a nFAULT pin.
