Description for the DRV8848
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 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 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.
