Part Number: TPS38

Hello,

We have a product uses TPS38B752933DSKR for reset control, the pin 1 - VDD is 13.8V.

I find the pin 6 - "CTR1/MR_N" hasn't external pull-high circuit.

I would like to know, does this pin 6 have an internal pull-high?

Hi JH,

The CTR/ MR pin of this device does not have a pull up resistor and it should not be connected to a pull up resistor or VDD. To utilize the MR functionality, the only valid inputs are GND and High-Z, or a capacitor connected to ground and the pin if configuring the reset delay is needed.
