STUSB4500, can the GPIO (or attach) pin be used to control a MOSTFET for a different power path

Hey STI am building an application that has two power sources, one USB-C (27W) with the STUSB4500 controller, and an optional DC input.Because the GPIO or attach pins can be open drain, theoretically they could be used to contrl a second FET on the p...

STUSB4500 PIN Capacitance I2C

Hello,What is the pin capacitance for SDA and SCL ? There is no information in the datasheet about this.Best Regard's,

I2C ISSUE in BLUENRG232. No data is written to TFR Tx FIFO resistor TDATA.

Now the issue concluded to the source of issue. The value of Dtata is 0x38 but its not getting transfered to TFR. Though for other resistors its working fine. The value of TFR always stays 0x00000000.  Since the data is not loaded to Tx FIFO, the com...
