Resolved! Capacitor at The AUX
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.
L6235
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...
VNF1048F Reverse current behavior
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...
SPV1050 MPPT resistor
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?
Lead acid battery management
Hello everyone. Does ST have battery management ICs for lead acid batteries or those that work with all chemistries?
Recherche transistor
Bonjour,Je viens d'ouvrir un ventilateur de refroidissement sur audiIl y a 7 transistors dont 2 sont cramé Il y a écrit dessus ST604342Mais impossible de trouver quoi que ce soit sur la toile.Quelqu'un peut-il m'aider Merci d'avance
Resolved! STP24DP05 IC queries
Hi Team, We are using this STP24DP05 (24-bit constant current LED sink driver with output error detection) IC for a X*Y array of diodes to get high or low. The IC is interfaced with microcontroller using SDI pin of STP24DP05. We have some doubts kind...
VNF9Q20F OUT CONTROL USING DIO PINS
Hi Everyone, I'm working on VNF9Q20F and VNF9D5F , I have an issue where I can’t control OUT (ON/OFF) BY SPI or by DIO . Once the VNF is in normal mode. Below are the commands which are I ‘m sending: 0x0h: 0x0 0x00 0x3F 0xF1,0x03h: 0x0 0x03 0x3...
STC3115 wrong SOC estimation
Good morning,I'm currently using the STC3115 in my application for estimating the SOC of a 1000mAh LiPo battery.The application drain a quite costant current, between 20 and 25mA, so the coulomb counter should be an easy approach for monitoring the S...
STC3100 Calibration
Hi together, ive read in the Datasheet that the STC3100 can be calibrated.The GG_CAL Bit (Bit 3 in REG_MODE @ Adress 0) can be set to short the analog Inputs together, allowing to compensate for Offset Errors.But how do i have to use this Bit? Just s...
