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...

Hi, Could you please explain the function of HWLO pin in the efuse VNF1048F. Thanks & Regards,Midhuna
L6599AD latched shutdown
Hi.I am using the L6599AD without PFC.When a latched shutdown occurs, the reset condition requires VCC power to fall below UVLO.I'm using an offline high voltage buck ic to make 15V for the VCC power.The problem here is that the L6599AD has a small c...
L9963E both inductive and capacitor isolation in same device
Hi!I'm designing a BMS for 96 cells in total, but divided in 24 cells per board.So I'm thinking two L9963E on board, and then boards connected together with inductive isolation.But inside board capacitive isolation would be enough, between the two ch...
STC3100, can't write register (no last ACK)
Hi,I'm facing some really weird problem with STC3100. After powerup I try to enable operating mode by writing 0x10 value (GG_RUN bit) to register REG_MODE at address 0x00. I2C address is 0x70 as default. STC3100 sends ACK for I2C address, also for re...
PSI5
Hi everyone, I am trying to establish communication between the L9663 and an airbag sensor using PSI5. However, the behavior I observe on the oscilloscope is shown in the picture, with ramps instead of clear pulses. Since PSI5 uses the same wire to s...
