Power management

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...

Does anyone know the common mode input range for the current amplifier on an L4981?

STC3117: SOC level of Ri referred to by datasheet

For calculating the VM_CNF value the datasheet of the STC3117 gives the follwoing equation:VM_CNF = Ri * Cnom / 977.78,where Ri is the impedance of the cell.The impedance of the cell however depends on the SOC, so i wonder at which SOC the Ri is supp...
