Dear Infineon:

Current I have one device for choosing how to driver it.

  1. In direct mode with GPIO control of device. Which GPIO1 controls the DSG FET, another GPIO2 controls the CHG FET.
  2. Register Control can be configured as simple control mode. Logic: rising edge active? or level active?

Some comments for my reference? or data for my study?

Hi Simon,

MOSFET selection:

You can choose MOSFET in the below link based on your current requirement. VDs 150Vds ,

 Id @ 100 deg C should be 1.5 times your max current.

Gate Driver:

IRS2118

 Switiching MOSFET

Gate driver requires active high and Low to switching MOSFET. Below llink will give you detailed explanation about driving  MOSFET.

I have one question

Rising edge active or level active, is this about MCU internal thing?

Hi Vignesh:

Thank you for your support!

Battery nominal voltage is 57.6V, Max Voltage is 67.2V.

GPIO output voltage is 3.3V or 5V.

Would you please help to recommend one type of N-CH MOSFET for my study?

One driver by pin CHG/DSG which is reach to Vtop voltaeg.

Another driver by GPIO1,2 which is reach to 3.3V OR 5V.

Can I learn which parameters of MOSFET be decided to choose the rising edge active or level active?
