Type Ordering Code Package BTS Q67007-A9274 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 621L1.)
