IPS160H diag pin impedance
Hi ST-Communitydoes anyone know what the off-impedance of the DIAG pin is when the chip is not powered or UVLO? There is a grey resistor to GND in the "Figure 1. Block diagram" with no description. The datasheet also states a max. leakage current in ...
SPV1050 Battery charging in case of loading
Hello there, I am planning to design an environmental IoT sensor node and i would like to incorporate the SPV1050 IC since it covers my project needs. I did extensive reading of the datasheet and there are some things I would like to get cleared:1. d...
L6699 incorrect startup
Hello, I have an issue with the L6699. The controller initiates the start-up sequence but after a few pulses it stops permanently.I describe the application first:Vin=385VVout=39 to 60 VTransformer magnetization inductance Lm=127uHResonant tank induc...
SMPS working on 110V but not working on 220V
Dear Community,I was desinged a SMPS for my circuit which belowed picture. Its working on 110V AC and not any problem. But when I connect it to 220V AC output voltage is going down slowly and about 1 minute later its go to shutdown. I can not find an...
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...
