STEF12H60M
Hello.I'm using several STEF12H60M efuses on a controll board.The setup:The CLREF resistor is 20k, the CS resistor is 3.3k and the SS cap is 100nF. This puts the efuse triping on 6.1A.I'm controlling the efuse by pulling down the on/pd pin with a npn...
M4Z32-BR00SH1 MSDS
Hello.I have a bloated M4Z32-BR00SH1 battery which causes my SRAM not to retain any data. Does anyone know where can I get its Material Safety Data Sheet (MSDS)? Or may be at least an official documentation stating why it does not need an MSDS. Appar...
Why stdriveg600 high side driver loses pulses? Can someone help me?
The circuit diagram is as follows，C1 is 0.1uf，VCC is 6V。I have the following problem:with a 100khz pwm signal (Dead Time=300ns) and with a power supply around 50v, When the current frequency is 100hz, the high side driver of the ic stdriveg600 starts...

l6566bh-based smps design is failed to start up
In my SMPS board input is DC. When I am giving supply to SMPS board, upto 75V input, voltage at Vcc pin is zero and supply current is around 0.15 mA. At 80V, voltage at Vcc pin is 5.27V(mean) (max 5.6V) and supply current is 1.2mA but Vcc voltage is ...
Can STBC15 be used as the NFC WLC charging module of ST25？
我最近尝试实现NFC WLC功能，但是X-NUCLEO-NFC07A1中EH的能量输出仅为10mw，无法为NUCLEO-L476RG供电。直到我看了NFC无线充电功能，却没有找到电池充电芯片的细节，我可以用STBC15实现NFC WLC功能吗？

L9963 Evaluation Board GUI Error: Configure ID button does not work
I downloaded the NI Labview-runtime 2014, NI VISA-RUNTIME and FTDI driver.I connected the EVM to the PC via USB and connected VBAT_CELL pin to power supply with 20V and GND_B to GND of power supply (see below picture). As can be seen from the pictur...
STEVAL-L99615C Communication Response Error
We are trying to get the L9961 Demo App working, but running into problems. We are following instructions according to document UM3141. In section 3.1.1.1 "Script Selection," it says to select the script entitled "Voltage Acquisition Init - 5Cell + V...
DC DC Buck convertor design using L6986F not working on PCB Board.
hi all,i have designed DC DC Buck convertor using L6986F convertor for 3.3V, 5V and 12V output respectively with input voltage of 24V DC. we tested the circuit and observed that at 3.5V input we are getting same 3.5V at the output port of 3.3V,5V and...
LNBH26S Thermal Performance
I am testing the LNBH26S with 430mA load at 18V on both channels of the chip, and on the bench the LNB chip reaches up to 100degC according to a thermal camera. Is this temperature at this load normal for the LNBH26S? My device needs to be weather pr...
