Dual 5.0 A H-Bridge
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.
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
• 5.0 V to 36 V continuous with 24 V nominal operating voltage (transient
operation from 5.0 V to 40 V)
• 235 mΩ maximum RDS(on) at TJ = 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
• 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)
Applications
• DC motor control
• DC brushed and servo motor driver
• Copiers, printers
• Factory automation
• POS, ATM, vending kiosks
• Robotics
• Security camera control
• Ticketing, toll systems
