TLC3702-Q1: TLC3702-Q1

Part Number: TLC3702-Q1
Other Parts Discussed in Thread: TLC3702

Hi,

As per datasheet it is recommended that the input voltage should be in range from -0.3V to VDD.

and pin current should be limited to +/-5mA. 

I have to apply Automotive standard pulse 0f -600V with Ri = 20Ohm for 1ms duration.

which is clamped using TVS clamped diode to 78V.

Now  this voltage is passed through series resistor and clamped diode as shown.

which would result as maximum of 300uA input current for pin but voltage at pin is around -450mV for 1ms duration.

Then will the opamp pin get damage??.

I think as long as we are controlling the current within range the pin will not get damaged.

Need your suggestion on this.

with regards
