Data Sheet: Technical Data

Dual 5.0 A H-Bridge

34932

The 34932 is a monolithic H-Bridge Power IC in a robust thermally enhanced

package. The 34932 has two independent monolithic H-Bridge Power ICs in the

same package. They are designed for any low voltage DC servo motor control

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

device is powered by SMARTMOS technology.

Industrial

H-BRIDGE

Each H-Bridge in the 34932 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.

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

outputs. Two independent 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 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

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

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

• Temperature dependant current limit threshold reduction to allow for

continuous operation without shutdown

• Security camera control

• Ticketing, toll systems

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

states

• Sleep mode with current draw < 20 µA (each half with inputs floating or set

to match default logic states)
