BTS770G General Description
The BTS 770 G is a TrilithIC 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 RDSON 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.)
For minimized RDSON the two low-side switches are produced in the SIEMENS Millifet logic level technology (The comparable standard product is the BUZ 101AL).
Each drain of these three chips is mounted on separated leadframes (see P-DSO-28-9 pin configuration). The sources of all four power transistors are connected to separate pins.
So the BTS 770 G can be used in H-Bridge configuration as well as in any other switch configuration.
Moreover, it is possible to add current sense resistors.
All these features open a broad range of automotive and industrial applications.
