Advance Information

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 (PWM-ed) at

frequencies up to 11 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.

54-PIN SOICW-EP

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).

• 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 < 12 µA (each half with inputs

floating or set to match default logic states)
