Regards : L9396 IC need to clarify Schematic support for designing WSS pins for our application
We are using Part.no: L9396 for Wheel Speed Sensor circuit Designing and we chosen the same part , in that referred some documents for designing .which is provided on online and STMicroelectronics website. But we need some more clarity to designin...
L9963E, measuring battery AC Impedance or EIS
I'd like to use L9963E to measure the AC impedance of the battery at 1 kHz. It requires applying 100 mA current at 1 kHz to the battery and measuring the voltage at 1 kHz, probably with 10 kSample/second or more. Is it possible? Or should I use anot...

Resolved! Inquiry Regarding L9961 Datasheet
Hello, I checked the L9961 datasheet for information on the cell voltage protection function, but couldn't find the operating voltage. Other products usually provide Over Voltage Protection (OVP) for cells, but in the case of L9961, only the cell me...
Viper comp design
Hello everybody,I need to user Viper115HS or Viper222XS vith 15V 600mA output at non isolated buck topology. I was designed my Fb pin with 130K Ohm and 11K Ohm resistors. But I can not find right Comp pin configuration. could you write capasitor and ...
L9945TR Mosfet Pre-driver peak drive current
Good afternoon ST engineer。I'm developing a DC motor control hardware using the L9945 in H brigde mode 。But facing a problem: the datasheet haven't any description about the Mosfet Pre-driver peak drive current when using external drive resistors...
Resolved! STPMIC1APQR does not always turn on.
I have a circuit with pmic STPMIC1APQR and STM32MP157DAA1 processor. For reference, I take STM32MP157A-EV1.There are cases when STPMIC1APQR does not turn on every time you turn on the power (1 time out of 20-50 turns on). At the same time, the input ...
