Hello,
We are evaluating the STEVAL-STPM801 board, testing the STPM801 as integrated hot swap, soft start and oring protections device.
On the EVAL board the TM pins with nrs: 8, 13, 14, 27, 28, 29 are equipped with jumpers to select pull-up or pull-down, while in the datasheet of the STPM801 those pins must be connected to GND.
Also in the datasheet there is in chapter 5.1.5 STAND-BY mode enter/exit, in several graphs a pattern given for ENABLE-IN. I can not find the ENABLE pin.
However, on the EVAL board the signal connected to pin nr 8 in that figure 1 has the name TM_EN_1/2.
The TM lines are also feed to a jumper (e.g. JP17) with signal names like SPI1_*.
The difference between the Eval board and the datasheet makes it confusing.
- Which pin is the Enable pin (mentioned in chapter 5.1.5 of the STPM801 datasheet)?
- What is the functionality of the other TM pins?
- Is there a "hidden feature" in the STPM801 available?
Hope that anyone can clarify.
kind regards
