TPS7B63-Q1: Does the EN Pin have an internal pull-up or pull-down?

John Griffith

Part Number: TPS7B63-Q1
Other Parts Discussed in Thread: TCAN1043-Q1,

Hello,

I want to drive the EN pin of the TPS7B6350-Q1 device with the INH output of the TCAN1043-Q1. The CAN device's INH output is either driven high to VSUP through an internal high side PFET, or floating.

Therefore I want to know if there is any internal pull-up or pull-down on the TPS7B6350-Q1's EN pin? I couldn't find anything in the datasheet that gave a definitive yes or no. If there is not an internal pull-down resistor or current source, I will need to place an external resistor from the INH output to ground to ensure the net is low in low power mode.

Thanks!

Hi John,

There is no internal pull-up or pull-down on the TPS7B63-Q1 EN pin. The EN pin should be driven to either logic high or logic low at all times. Placing an external pull-down resistor to ensure logic low is a great idea for your application.

Very Respectfully,
Ryan
