Resolved! Question about charge pump of the L6395 driver
Hi everyone,I am using two mosfet as a switch (in order to open or close a contactor, turn-on or turn-off some PCBs, etc, not high frequencies are required), one high side mosfet and one low side mosfet. I want to control them with the L6395 driver.W...
SPV1050 - can LDO pins be grounded?
Hi, I am designing an application using the SPV1050. I am not using the LDO function, and am only using the SPV1050 for charging my battery.I have tied LDO1_EN and LDO2_EN to ground. Can I safely ground the LDO1 and LDO2 pins as well in this configur...
Getting real time ADC data out of STPM32
Apart from the V_RMS, I_RMS, power and energy (all aggregated), is it possible to output the ADC readings real time over SPI? I am looking to get 8k samples of I and V out of it. As of it was a pure ADC, with the filtering, but without the calculatio...
Resolved! TL431 Marking Code (431CH)
Hi,Please help with the "TL431CDT"There is "H" symbol on the marking code (431CH)What does it mean?There is nothing is the datasheet (marking 431C without H).Best regards and thank youLuca
Resolved! What should I do with STPMIC1 unused pins ?
Hello,I'm designing a board based on STM32MP1 and we decided to use the STPMIC1A to manage the power. The board is really simple and so we use only the bucks (1 for core, 2 for ddr, 3 for vdd and 4 for extra 3.3). All others (LDOs; boost and switches...
How can avoid overlapping of pwm from different channels?
I am writing a simple 6 step bldc motor control using Hall sensor(Complementary PWM).When I try to switch the pwm(example when HALL input changes from 110 to 101) channel 1 and channel 2 gets over lap.I have inserted Deadtime.One in red is channel 1...
Resolved! 16 Channel Adjustable Constant Current LED Driver
I'm looking for a drop in replacement for the TI TLC5926IPWPR LED driver.It's 16 channel constant current LED driver. Max current is set via an external resistor, but we can also adjust the current via the SPI interface.Does ST have this as well? I d...
