Part STM6904 Doc ID 14289 Rev 3 Pull-up on /rst output open-drain in Table 2. Signal names and functions on 8 RST Output Active-low open drain reset output (10 kΩ internal pull-up) I think the note (10 kΩ internal pull-up) was meant for pin 1

From the rest of datasheet and also from the test we have performed preparing a test circuit it looks like there is no pull-up on the output (as it should be for an open drain), if so please update the datasheet. Please confirm if we are right or oth...

Stef01 - output voltage issue

We are using STEF01 e-fuse with 24V input at VCC. See schematic below for your reference. Without any load connected at Vout pin we get around 22.73V (with Vclamp floating).If Voltage is clamped to 28V(ie:R5 -300Kohm and R4 -10Kohm) then we are getti...
