Siemens BTS 770 G User Guide (1)(1)

Summary

The BTS 770 G is an advanced quad switch driver integrated circuit designed for highly efficient DC motor management and power applications. This compact device integrates both high-side and low-side switches into a single package, minimizing thermal resistance and eliminating the need for bulky heatsinks. The technical manual provides detailed information on its H-Bridge configuration, comprehensive protection features (like overcurrent and short circuit detection), pin functions, and electrical specifications. It is the ideal solution for sophisticated performance-critical systems in both automotive and industrial sectors.

Type Ordering Code Package BTS Q67007-A9254 P-DSO-28-9

Description The BTS G is a Trilith IC contains one double high-side switch and two low-side switches in one P-DSO-28-9 -Package.

“Silicon instead of heatsink” becomes true

The ultra low RDS

ON of this device avoids powerdissipation. It saves costs in mechanical

construction and mounting and increases the efficiency. The high-side switches are produced in the SIEMENS SMART SIPMOS® technology. It is fully protected and contains the signal conditioning circuitry for diagnosis. (The comparable standard high-side product is the BTS 611L1.)
