Power management

Hallo community, Can you please verify my schematics using STC3117 fuel gauge IC.

In the schematics, the IC is connected to the battery recharging and protection circuit (MCP73831T and BQ29700 respectively). The BATD feature is not used. The confusion arises where the STC3117 is connected across the protection circuit. The battery...

I am using STM32 controller with stbc02 battery charging chip from st for monitoring the battery level voltage. While trying to read the battery adc voltage from BATMS pin,it always shows 0.How to set the battery to be in working mode?

We are using the STEVAL-STWINKT1b, where shutdown works great, but if there is anything connected to STMOD+ it still draws current. How can we shutdown the VDD of the STMOD+ connection port?

STEVAL-STMODLTE + STEVAL-STWINKT1B in shutdown mode consumes more current.

Hi, We notice that in Shutdown mode STEVAL-STWINKT1B + STEVAL-STMODLTE is consuming more power[36mA] than specified. But if we us only STEVAL-STWINKT1B than the current consumption is in nA, that's great but not when we plugin STEVAL-STMODLTE, it sh...

STC3115 SOC show wrong

Hi, started using chip STC3115 in custom designed PCB. Everything is work fine, voltage and current measure good. But If I charging the battery SOC doesnt show correctly. I using it with driver from official STM site. I connected to chip 12500mA Li-p...

STUSB4500 ATTACH pin use for detection of Cable attached to the Type C port

Hi,we ar designing a Tupe C Power Delivery and Communication on a single USB type C port. SO, if we are not connecting any device to the USB port , then the communication circuitry must be off and should not consume any power. and when the source is ...

I'd like to porting software from P-NUCLEO-IHM03

I'd like to porting software from P-NUCLEO-IHM03 (NUCLEO-G431RB + X-NUCLEO-IHM16M1) to NUCLEO-G474RE+ X-NUCLEO-IHM16M1. Are there hardware differences between NUCLEO-G431RB and NUCLEO-G474RE that exclude such software porting?I installed on my PC sof...
