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 • The specifications for the product described in this document are for reference only. Upon actual use, therefore, please request that specifications to be separately delivered. • The application circuit examples explain typical applications of the products, and do not guarantee the success of any specific mass-production design. • Application circuit diagrams and circuit constants contained herein are shown as examples of standard use and operation. Please pay careful attention to the peripheral conditions when designing circuits and deciding upon circuit constants in the set. • Take account of common impedance when designing the earth line on a printed wiring board. ■ ORDERING INFORMATION ORDER NO.
