I am using STC3115AIQT GAS GAUGE IC for battery monitoring...but i am not able to detect the current value even though i have resistor connected to CG and GND...i am getting only the voltage value....can i get solution for this

Resolved! Implement s-ramp on stepper

Hi, I need to implement an s-ramp for a stepper motor.Currently using L6482.Can you please point me in the direction of the correct controller + driver? Thanks!Uri

Resolved! Drive 2 motors simultaneously

Hi all,I'm using L6482H stepper.The need has arisen to drive 2 motors simultaneously, with the same profile.I was thinking about daisy chaining the SYNC output of the first driver with the STCK of the second driver. But I understand that this will n...

STC3100 Battery Monitoring issue

I am using STC3100 Battery monitor IC with Coulomb counter/gas gauge IC for measuring by 2500mAh Li-ion battery capacity over I2C interface with my Nordic NRF52 BLE SOC chip . I have followed the reference design which is provided in the datasheet ( ...

How does the L6599 LLC control chip know when to soft switch? The resonant current input is filtered and not cycle by clcle.

As I understand it, to initiate soft switching, the MOSFET devices need to be switched when the resonant current passes through zero. How does the L6599 know when to do this?Cheers & thanks,DG

we have 2 STM labels for STN3P6F6, which PBT difference, 260 C and 210 C, would you help to check what is difference or STM has PCN to changed this information, thanks,
