... Overview The BTS 7970B is part of the NovalithIC family containing three separate chips in one package: One p-channel highside MOSFET and one n-channel lowside MOSFET together with a driver IC, forming a fully integrated high current half-bridge. All three chips are mounted on one common leadframe, using the chip on chip and chip by chip technology ...

... Power Stages The power stages of the BTS 7970B consist of a p-channel vertical DMOS transistor for the high side switch and a n-channel vertical DMOS transistor for the low side switch. All protection and diagnostic functions are located in a separate top chip. Both switches can be operated kHz, allowing active freewheeling and thus minimizing power dissipation in the forward operation of the integrated diodes ...

... In combination with a typical inductive load, such as a motor, this results in a switched mode current limitation. That way of limiting the current has the advantage that the power dissipation in the BTS 7970B is much smaller than by driving the MOSFETs in linear mode. Therefore it is possible to use the current limitation for a short time without exceeding the maximum allowed junction temperature (e ...
