Dual 4.0 A Power H-Bridge

The 33922/34922 is a dual H-Bridge Power IC with a load current feedback

feature making it ideal for closed-loop DC motor control and bipolar stepper

motor control. The IC incorporates internal input control logic, charge pumps,

gate drivers, and low R_DS(ON)output MOSFETs. The 33922/34922 is able to

DUAL 4.0 A POWER H-BRIDGE

control two inductive loads with continuous DC load currents up to 4.0 A.

Output loads can be efficiently pulse width modulated (PWM-ed) at

frequencies up to 20 kHz. The load current feedback feature provides a

proportional (1/375th of the load current) constant-current source output

suitable for monitoring by a microcontroller’s A/D input. This feedback feature

facilitates the design of closed-loop torque/speed control.

Two fault status terminals (SFA, SFB) report undervoltage, short circuit, and

overtemperature conditions separately for each H-Bridge. Each H-Bridge has

two independent inputs providing polarity control of the outputs. Two disable

inputs on each H-Bridge provide a choice of high=true or low=true shutdown

of the H-Bridge outputs.
