TPS3126E12 RESET output voltage.

Q: TPS3126E12 RESET output voltage. by 1454843

Dear Team,

Customer is asking why the open-drain type output voltage is limited to Vmax = Vdd+0.3V ?

Can we explain this to customer ? 

Thanks.

The TPS3126 /RESET pin has an internal diode to VDD, so you can not pull this pin higher than VDD.  If you must pull /RESET higher than VDD, I suggest a diode with anode on /RESET and cathode on VDD. 

TPS3123, TPS3124, TPS3125, TPS3126; TPS3218
