Hi
we are using TS3A4751RUCR in one of our designs.
The "In1 to In4" inputs are connected together and pulled down with 20K resistor and controlled by a GPIO of uC. we observe an issue when the Controller tries to enable (pulling the IN inputs to 1.8v) and the switch is not functioning as intended. The schematics is attached herewith or your reference. The drive strength of microcontroller is 2mA to 12mA.
1. what is the input capacitance / load capacitance of "In" inputs?. we couldn't find the details in the datasheet.
2. can the In1 to In4 be connected together and if connected together what is the drive current required by the "driver" (microcontroller)?
3. Do we need to improve anything on the attached schematics?
Best Regards,
Siva
