Preliminary data sheet
7.11 High- and low-side drivers
The signal from the IC is a voltage signal and the signal to the IC is a current signal. In this
way a driving conflict is prevented. Also it leaves the possibility for the outside world to see
the signal from the IC even while a fault condition is being signalled to the IC in the mean
time, as illustrated in
The four drivers are identical. The output of each driver is connected to the equivalent
gate of an external power MOSFET. The bootstrap capacitors are charged from the VDD
voltage when the low-side power MOSFETs are turned on, and they supply the high-side
drivers. The VDD voltage directly supplies the low-side drivers. Current sourcing capability
and the on-resistance of the drivers can be found in
