• Description: 5-A H-Bridge for DC-Motor Applications
• Manufacturer: INFINEON [Infineon Technologies AG]

Application Modes
1. Simple CW/CCW-Control
2. Sign/Magnitude Control
To achieve motor counter clockwise turning change input signals to:
IN1 = PWM; IN2 = H.

3. Locked Anti-Phase Control
Data Sheet
For low-cost application simple CW/CCW-Control without any speed regulation is
recommended. A low-speed two-line interface is sufficient for the brake low,
clockwise, counter clockwise and brake high command.
For this mode two ports with PWM capability are necessary. Motor turns clockwise
(current flows from OUT1 to OUT2; means: OUT1 is switched HIGH continuously and
OUT2 is PWM controlled.
The most important advantage to drive a motor in locked anti-phase mode is: Only one
variable duty cycle signal is necessary in which is encoded both direction- and
amplitude information. So the interface is very simple: A PWM input driven by a
dedicated PWM port from µP.
