MasterGAN bootstrap supply question
Hi all,I am using a MasterGaN5 to drive an electro-optic crystal. The switching rate is variable and can go up to 1-2 MHz, while at times I need to apply a constant high voltage to the crystal. My solution was to use an external isolated 5.5V suppl...
Resolved! STBB3J Feedback Voltage Resistors
Hello, I'm new here. I'm doing a project with STBB3J components and I believe I didn't correctly understand how to calculate the resistors that control the output voltage. I followed the example of the same application circuit, which is this (page 4 ...
Steval-L99615C Discovery Kit
When testing discovery kit. With Demo 1 binary file FW of the STSW-L9961BMS. Tera Term serial monitor outputs random characters. Using Speed 9600, Data 8 bit, Parity none, Stop bit 1 bit. Tried different computer. Tried different settings. Same resu...
Standby Mode Control to minimize power consumption (STM32L476RCT)
My name is Lee Dongjin from South Korea and I am developing the system below.While developing a "Multi-Point Correlation Leak Detection System" using your company's MPU (STM32L476RCT), the following problem occurred and I would like to ask for a solu...
Can STEVAL-SPIN3201 be programed for 6step?
Hi,I was wondering, if you can programm STEVAL-spin3201 board to 6-step mode, instead of FOC?
Regarding availability of low side switches
Hi, Can you please let me know the availability status of low side switchesRequirements:Support more than 60V of battery Voltage and qualified for automotive application.Load Current should be up to 4ASupport over voltage and over current protection....
VND5E006ASP-E Max Voltage Output for CS pin
To confirm, the max output voltage on CS pin (I assume it is called VSENSEH) is 8V according to Table 8 on p11 (https://www.st.com/resource/en/datasheet/vnd5e006asp-e.pdf). But I assume this depends on the sense resistor and ISENSEH of 7mA. What is...
Resolved! Setting reference voltage with battery monitor li-soci2(3.6v) battery *Vrefint
hello everyone,In a battery-powered IoT project, I can never make accurate measurements because my battery voltage is the same as my reference voltage. I did not use any power ICs to reduce the cost of my project.I am using a 3.6V li-soci2 batterySav...
