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...
Issue with STC3117 Fuel Gauge Resetting Repeatedly
Hi,I am using the STC3117 fuel gauge, but my IC keeps resetting repeatedly, so I am not getting any voltage or current readings. However, I am getting the correct values for other registers, such as the device ID and temperature.I tried to debug thi...
L4986A
I am using Simlis to carry out a simulation of AN5797 1KW bridgeless CCM-PFC pre-regulator based on the L4986A IC, I have built up the circuit, but it does not simulate and produces an error The voltage and currents of this circuit cannot be uniquely...
