Having 2 power rails, 3V3 and 5V while STNS01 generates 3V3 (well, 3V1 to be exact) from 5V input (or battery), is it possible to feed 3V3 externally when STNS01 is shutdown? Is STSN01's LDO output reverse protected? Or will we need an ideal diode to...
Repair ECU 7SM Magnetic Marelli Need more Detail this chipThanksBest Regards
Hi all,Is anybody known something about this power supply? What I know is:There is an ST logo on the board.Input: ~240VACOutput: 12VDCusing 1NK60Z and TL431 in TO92 packageThere are four component blown out. One of the blown out 3 pin component marki...
I'm using the STC3115 driver provided by ST and am having a strange issue with the STC3115 on a custom board. I've hooked up an o-cope and am monitoring the data being sent over I2C. When I write any of the registers in the STC3115 it ACKs the data b...
Hello,I am using a STNS01 in my circuit for the power management. The problem is when I only have a charged battery (4.1 v) connected to the BAT pin, it does not switch to the battery voltage. As if the chip is in shutdown mode (I do not know why, th...
I have PWM to control motor at each channel. One is limited by 0.3A and the other one is limited by 0.1A by voltage divider reference to 5V. By using this approach, as my understand I can not reach to OCD feature because the current can not reach to...
I am currently planning on build a low voltage 3 phase AC power supply for powering my DIY axial motor. I am scared if I input high voltage say 60V, it may have a chance of leak of current going to the micro-controller. I cant find any protection men...
Hi dear,I designed a step motor driver board with L6470h and tested it. There are some problems with the board.I set the run current, hold current, ACC, ACC current, DEC, DEC current at the fixed value, and then changed the MAX speed, then the actual...
Using STM32F407 comparative output function, we generate 57600Hz square wave. I find that there are some fluctuations in square wave. Observed by oscilloscope, the rising and falling edges of square wave have several ns fluctuations. So I want to kno...
I am designing stepper driever using L6470PD.Is it possible to isolate system power and motor driver power?I wonder L6470PD internal connection. Is there related document?I want to design power line like the picture below
