SPV1050 - 100mV on BATT pin and no output on LDO2?

Hi! I'm working on a project using SPV1050. The configuration and schematic for my device is as on the schematic below. I'm providing 4.3V on line PV+ (pin20), yet I have only 100mV (not rising) on BATT pin and absolutely no output on LDO2 pin. Why c...

TVS uni-directional diode

A TVS diode labelled as SJ 5C.What would be the value of the TVS diode? Thanks

I have a STEVAL-POE001V1 development board. connected to a Planet FSD-10088hp switch https://www.planet.com.tw/en/product/fsd-1008hp. I have removed R15. LEDs D2 and D13 blink on and off. Do you know why this is?

Why does the LD39050 have a maximum capacitance value?

We have been seeing some intermittent failures of the LD39050 in our products. I can't see anything wrong with the design other than the output capacitance. The datasheet specifies a maximum of 22uF for stability, but our design has approx 30uF on th...

Hi, I plan to use the TSC212IYCT for 0-1250nA current measurement. Is there any tools I can use to simulate the circuit before I build it?

I only saw there are few options for current sensing using your tool and I cannot set the current below 6A. I need to make a current shunt to measure 0-2000nA

is it possible that stdriveg600 high side driver loses pulses for high duty cycle?

hello, I bought the evaluation board EVSTDRIVEG600DG and I made the circuit in the figure below. I have the following problem: with a 50khz pwm signal (Dead Time=200ns) and a duty cycle of 90% with a power supply around 100v, the high side driver of ...

Can we have Source Code of STEVAL-ISA147V3 SMPS Module for Firmware Development?

Where do you connect the EP of the L9822EPD? I guess it doesn't need to be connected anywhere. But can I connect it to GND?
