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 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  
• 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)
