Gate drivers

The STSPIN32F0A device integrates a triple half-bridge gate driver able to drive N-channel

power MOSFETs or IGBTs. The high-side section is supplied by a bootstrapped voltage

technique with an integrated bootstrap diode.

All the input lines (refer to Figure 2: "Analog IC block diagram") are connected to

a pull-

down resistor (60 kΩ typical value) to guarantee the low logic level during the device

start-up.

The high- and low-side outputs of same half-bridge cannot be simultaneously driven high

thanks to an integrated interlocking function.

All the input lines of the analog IC have an internal pull-down to guarantee the low

logic level during the device start-up and when the MCU lines are not present.
