DRV8256E/P H-Bridge Motor Driver With Integrated Current Sense and Smart Tune

Technology

1 Features

3 Description

•

N-channel H-bridge motor driver

– Drives one bidirectional brushed-DC motor

– Two unidirectional brushed DC motors

Integrated current sensing and regulation

4.5 V to 48 V Operating supply voltage range

Multiple control interface options

– PHASE/ENABLE (PH/EN)

The DRV8256E/P devices are single H-bridge motor

drivers for a wide variety of industrial applications.

The devices integrate an N-channel H-bridge, charge

pump regulator, current sensing and regulation, and

protection circuitry.

•

Integrated current sensing allows the driver to

regulate the motor inrush current during start up and

high load events. A current limit can be set with an

adjustable external voltage reference. The integrated

current sensing uses an internal current mirror

architecture, removing the need for a large power

shunt resistor, saving board area and reducing system

cost. A low-power sleep mode is provided to achieve

ultra-low quiescent current draw by shutting down

most of the internal circuitry.

– PWM (IN/IN)

•

Smart tune, fast and mixed decay options

Low R_DS(ON): 165 mΩ HS + LS at 24 V, 25°C

High Output Current Capability: 5-A peak

Limits inrush current of brushed-DC motors

Configurable Off-Time PWM Chopping

– 7, 16, 24 or 32 μs

•

Supports 1.8 V, 3.3 V, 5.0 V logic inputs

Low-current sleep mode (2 µA)

Spread spectrum clocking for low EMI

Protection features

– VM undervoltage lockout (UVLO)

– Charge pump undervoltage (CPUV)

– Overcurrent protection (OCP)

– Thermal shutdown (OTSD)

Internal protection features are provided for supply

undervoltage lockout (UVLO), charge pump

undervoltage (CPUV), output overcurrent (OCP), and

device overtemperature (TSD). Fault conditions are

indicated on nFAULT.
