... AEC Qualified Description The BTM7752G is a fully integrated high current H-bridge for motor drive applications. It contains two p-channel highside MOSFETs and two n-channel lowside MOSFETs with an integrated driver IC in one package. Due to the p-channel highside switches the need for a charge pump is eliminated thus minimizing EMI. Interfacing to a ...

... Power Stages The power stages of the BTM7752G consist of p-channel vertical DMOS transistors for the high side switches and n-channel vertical DMOS transistors for the low side switches. All protection and diagnostic functions are located in a separate control chip. Both switches, high side and low side, allow active freewheeling and thus minimize power dissipation in the forward operation of the integrated diodes ...

... Overtemperature Protection The BTM7752G is protected against overtemperature by integrated temperature sensors. Each half bridge, which consists of one high side and one low side switch, is protected by one temperature sensor located in the high side switch. Both temperature sensors function independently. A detection of overtemperature through temperature sensor leads to a shut down of both switches in the half bridge ...

... In combination with a typical inductive load, such as a motor, this results in a switched mode current limitation. This method of limiting the current has the advantage that the power dissipation in the BTM7752G 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 ...
