Type Ordering Code Package BTS Q67007-A9336 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.)
