3 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.
