Is it possible to use a Qi2 rx coil with magnetic array on a stwlc38 design? The goal is to use a Qi2 charger and reap the benefits of magnetic alignment and 15W charging while still being on the Qi1.3 standard of the stwlc38.
Hi, I am currently working on a project that uses a BLDC motor (42BL90L2-3), and I am trying to drive it using a DRV8323 gate driver. I have been using the ST MC workbench (version 5.4.8) to profile the motor and control unit, but when I try to gener...
Hello,I use the Viper06LS in the Buck Converter topology.The input voltage can vary between 100V and 530VDC. The output voltage is regulated to 10 V. (See "Viper_circuit"!)Unfortunately, a problem arises when the input voltage increases to approx. 52...
Hi all,We're using the STC3115 for a single-cell lithium battery, the main goal is to provide a SoC that gives the user a feeling about remaining battery life.This is working quite well when we're draining the battery completely, even in very differe...
Dear Engineers pls comment on my Querys.... Is it possible for UC3845 Mosfet driver IC to accommodate non-isolated converters? Additionally, could you please clarify which can control MOSFET switches in a Buck converter?
Hi, i design a SPMS with VIPER013HS and in the design schematic, i dont know the purpose of the capacitor in attached picture. Also in design, there is no capacitor value mentioned for this capacitor.
Hi I want to use a L6235 to control a BLDC motor, but do not have a micro to control the loop. Micro not an option. The are two options I have is to use an integrator as per datasheet or use app note DT0001 mention using the Tacho output and the FWD...
Hello,I am planning to use the VNF1048F as a eFuse for my current project.From the datasheet it is not clear to me which is the behavior of the VNF1048F in case of reverse current.Does it automatically close the MOSFETs (to avoid diode conduction), d...
There is confusion about resistor values on input voltage divider.According to datasheet voltage on MPP pin should be lower than 2.1 V (Vuvp - 0.1V)In application note AN4397 you used UVP set by resistors R4, R5, R6? Which value should be used?
Hello everyone. Does ST have battery management ICs for lead acid batteries or those that work with all chemistries?
