Description

The EVLDRIVE102BH evaluation board is a three-phase inverter based on the

STL220N6F7 power MOSFETs. This evaluation board allows a full evaluation of the

features of the STDRIVE102BH, a triple half-bridge gate driver.

The power stage uses a three-shunt topology: the current sensing and the

overcurrent protections are implemented using the three operational amplifiers and

the three comparators embedded in the STDRIVE102BH.

The embedded protections of the STDRIVE102BH, such as the UVLO on the driving

voltage and the VDS monitoring for each power MOSFET, ensure a safe driving

operation of the power stage.

The EVLDRIVE102BH evaluation board is thermally protected by exploiting both the

hardware thermal shutdown protection embedded in the STDRIVE102BH and also

an onboard NTC sensor placed close to the power stage, for a firmware thermal

protection.

The two diagnostic pins of the STDRIVE102BH, the nFAULT pin for the protection

events and the FLAG pin for the drivers’ supply warning, are both connected to the

control board and are also visible through two different LED indicators.
