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...
Resolved! Shoot Through - Bootstrap Capacitance Question
I'm seeing shoot through on the coil drives for the STSPIN32F0A custom implementation in the attached schematic. The attached scope shot has these channels:CH1: 24VCH2: CoilCH3: Low Side GateCH4: High Side GateYou can see the 700ns of deadtime when t...
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...
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...
Resolved! L6206Q Power Supply Range
Hi, I am just wondering would it be ok to operate this IC with 52 to 55V supply? Hoping to use this with a 52V battery without the trouble of designing a new power supply.Clipper circuit will also be incorporated to eliminate any voltage spikes.Regar...
Hi, As a part of our new product, we have decided to run the product on PD capability. So, we have decided the product to be developed with two USB PD ports, so that one port can be used for Wall PD charger and other port for PD by laptop.
We have decided to use STUSB4500 for stand alone PD controller, But the main struggle is to coordinate these two PD ports and switch between them as availability.Priority is given for Wall charger PD port and the other port is used for PD when Wall c...
