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...
SPV1040 Light Load Efficiency
What is the SPV1040 MPPT Charger's light load efficiency? In my application, the power from the Solar Panel goes down to 10mW. So, I'm interested, to know the output of SPV1040T when the input power is only several mW. From the datasheet, my applica...
SPV1050 No Voltage at the LDO-Out Pins
Hi all,I connected my SPV1050 chip as you can see in the picture and started to measure my circuit. It looks pretty good. I powered it up with 3.3V at IN_LV. And I can measure a voltage of about 2.416V at the STORE pin. And even the LDO2_EN pin got a...

STNS01 not shutting down properly
Hello, I have a simple circuit with an STNS01 charging a 150mAh single cell battery and am using the LDO to power an STM32F042 and a couple of other small devices. It mostly seems to work OK, however if I pull the SD line high using the micro (or an ...
Resolved! Viper319 Not performing for load more than 4W
I have attached the Actual Circuit as image. We have gone for flybuck topoogy.Input VBus = 335VDC. We require 15VDC, 600mA for Load Requirements. (9W Least Requirement)As per datasheet VIPER319HDTR is capable of delivering 19W. We designed the PCB Bo...
