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...

cascade clock feed of multi STPM3X chips?

Hi, I would ask a question about STPM3X, when I use multi chip of STPM3X, I can use One crystal and then cascade clock feed (Figure 27 in datasheet). Does this change the performance and the power consumption for the first master chip and slave chip?

Resolved! About Part#T2535-600G.

Could you please help check the normal range of resistance vaule between Pin A1 and Pin G ? Will it be higher than 72.5ohm? Or will the resistance vaule become higher due to some manufacturing process?

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...
