Hello Volt.Tech experts, Can STSPIN32F0 or STSTPIN32F4 to drive the SiC/ GaN mosfet by the specification of Rdson = 73mOhm, 650V and 26A? Thank You Vikas Nagpal

We’re using the L6920 to drive a 1-watt LED.
We’re trying to apply the under voltage cut-off ( lockout) too. We chose the values of the voltage ground connected to the LBI pin similar that the value that comes to say 3V. Still, the IC didn’t shut off at 3V.
We also tried connecting the LBO to Vout with a 200K resistor in between. Even this didn’t work.
Can someone help apply this circuit?
Thanks!
Hi Ashish, However, you would notice that LBI input is connected to LBO output and that's the only purpose of this input, If you look into the block diagram of L6920 in its datasheet. LBI input doesn't shut down the output! Still, you need to use LBO output to shut down accordingly, If you require tRead more

The current is specified in the test conditions, the Voh and Vol is specified for a load of 1mA(for push-pull). The nRESET can be treated as the GPIO characteristics.

Hello @Vikas, The GaN FETs need specific gate drivers (e.g. STDRIVEG600). The STSPIN32G4 is suitable to manage motor supply voltage from 5.5 V to 75V. In the STSPIN32F0 family the part number STSPIN32F060x could be used. The driver has 20 V of maximum operating voltage and it isn't suitable to driveRead more
Hello vikas Nagpal,
The GaN FETs need specific gate drivers (e.g. STDRIVEG600).
The STSPIN32G4 is suitable to manage motor supply voltage from 5.5 V to 75V.
In the STSPIN32F0 family the part number STSPIN32F060x could be used.
The driver has 20 V of maximum operating voltage and it isn’t suitable to drive negative voltage.
However, you can apply them, If these characteristics are compatible with your SiCs.
Thank You
