SPV1040 Not working
Hi,I have been working with SPV1040 and L6924D ICs. The SPV1040 doesn't seem to work in my design. I have designed the circuit and layout based on this app note. Without connect the battery for the first time. The SPV1040 generates 4.1V at output but...
How does STEVAL-ISV020V1 provide LDOs when the PV panel hasn't sunlight?
I am working with STEVAL-ISV020V1 and I have a PV pannel and a battery connected with 3.3 V close to the maximum capacity.When we don't have power supply on PV panel, shouldn't the battery voltage supply the system?for example, shouldn't it have 1.8V...
Resolved! How to use internal opamp in stspin32f0602
I have been using stspin32f0602 based on evspin32f0602s1. But the evaluation kit uses external opamp and comparator ic. I am looking for a way to use the internal opamp and comparator for amp measurements for easier hardware and inventory management....
VIPER26L compatibility with VIPER26K
Hi, we are using VIPER26LDTR in a non-isolated AC/DC converter with 220V AC line input and 16V DC output. Can we replace the chip with VIPER26K version without changing the circuit/PCB? The K version has a MOSFET capable to withstand 1050V but apart ...
Hello, We are going to develop a 3 phase interleaved PFC for 30kW. I want to apply STNRGPF01, but it is marked as NRND. I wonder if there is any reason why it should not be used or discontinued.
If there is a clear reason for not being used, can you recommend another part?We can't do fully digital programming.
Resolved! How to drive the BOOT pins of a STSPIN32F0251?
I have an EVSPIN32F02Q1S1 board to experiment. Each boot pin has a connection to Vcc via a diode (D1, D4, D7) - which are not mounted on the board. When driving a phase full on the pull up MOSFET breaks down about every 2.5ms. The time varies dependi...
H2PAK-2 vs H2PAK-6 MOSFET package for high current application
I'm using multiple MOSFET of STH310N10F7 in parallel for current of approximately 60A.MOSFET are used in DC Bias and not switching so time delay is not a factor of consideration.I'm confused between the packages.What are intended application of H2PAK...
Beginners question: IHM01A1 + Stepper - What am I doing wrong
I am an owner of the STEVAL-EDUKIT, an inverted pendulum kit by ST with an NUCLEO-F401RE, IHM01A1, Nema17 motor and an rotary encoder + a 2A, 12V power supply. I have no prior experience with motor control whatsoever. See https://www.st.com/content/s...
Which pin is used as output for connecting load on spv1050 ? i need to connect load .
i am trying to charge li ion battery. the power should be available all the time , even if there is no harvesting in process.#Spv1050
