Description

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 with 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 DRV8848 is capable of driving up to 2A of current from each output or 4A of current in parallel mode (with proper heat sinking, at 12V 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.
