Technical Data

5.0 A H-Bridge

34931

The 34931 is a monolithic H-Bridge Power IC in a robust thermally enhanced

package. It is designed for any low voltage DC servo motor control application

within the current and voltage limits stated in this specification. This device is

Industrial

H-BRIDGE

The 34931 H-Bridge is able to control inductive loads with currents up to 5.0 A

peak. RMS current capability is subject to the degree of heatsinking provided to

the device package. Internal peak current limiting (regulation) is activated at load

currents above 6.5 A ±1.5 A. Output loads can be pulse-width modulated

(PWMed at frequencies up to 20 kHz. A load current feedback feature provides

a proportional (0.24% of the load current) current output suitable for monitoring

by a microcontroller’s A/D input. A status flag output reports undervoltage,

overcurrent, and overtemperature fault conditions.

32-PIN SOICW-EP

Two independent inputs provide polarity control of two half-bridge totem-pole

outputs. The disable inputs are provided to force the H-Bridge outputs to tri-state

(high-impedance off-state).

Features

Applications

• DC motor control

• 5.0 V to 36 V continuous operation with 24 V nominal operating voltage

(transient operation from 5.0 V to 40 V)

• DC brushed and servo motor driver

• Copiers, printers

• Factory automation

• POS, ATM, vending kiosks

• Robotics

• 235 mΩ maximum R_DS(on)at T_J= 150 °C (each H-Bridge MOSFET)

• 3.0 V and 5.0 V TTL/CMOS logic compatible inputs

• Overcurrent limiting (regulation) via internal constant-off-time PWM

• Output short-circuit protection (short to VPWR or GND)

• Temperature-dependant current-limit threshold reduction

• All inputs have an internal source/sink to define the default (floating input)

states

• Security camera control

• Ticketing, toll systems

• Sleep mode with current draw < 20 µA
