5.2
The power stages of the BTN7970 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 up to 25 kHz, allowing active freewheeling and thus minimizing
power dissipation in the forward operation of the integrated diodes.
