an external H-Bridge output driver that handles the high current going through the motor.

This output of this block will be turned on or off with each input pulse based on the status

of the directional logic. The PWM drive techniques provide the benefits of reduced power

dissipation, improved servo motor performance and positively affect system efficiency.

(7) Output driver

The output driver controls the servo current direction. For light load application, the servo

can be connected with OUT1 and OUT2 pin only. For heavy load application, the EXP1

and EXP2 pin will be connected to the base of the external PNP transistor. It drives in an

H-bridge configuration (The sink NPN drivers are built inside the chip).

■ NOTES ON USE
