BTA24-800CW can't switch off 60 W resistive lump
i am using MOC3063 as an optocoupler and BTA24-800CW as a triac .with 220 V ac and it worked fine (switch on and off) with the 10W,5W,3W resistive loads but when using 60 W incandescent lump it only turn on but not off i am using this basic circui...
Resolved! STEF01 VCC/GND in a -48V system
Hi Sir, For a system with -48V and 0V (Ground) power rails, can I use the STEF01 with the following connections?Connect the IC's GND pin to the system -48V rail.Connect the IC's VCC pin to the system 0V rail. Will the chip work correctly and safely ...

we want to know that. Can this IC E-Fuse capable to handle negative transients (350 ms) of -40 Volt.Please Reply ASAP.MPN: STEF01
Resolved! [BLDC] How to get trapezoidal back-emf waveform
Hi All,I'm working on driving sensorless BLDC motor by 120 degrees trapezoidal control.I'm stuck on to get back-emf voltage like below figure:My result is like this.And the circuit used for voltage sens part is as follow.I don't know if it's a circui...
SCT040W120G3AG Spice model incomplete
The SPICE model file for the product SCT040W120G3AG downloaded from the official website is incomplete, it only has the LIB format file. Can someone provide me with the complete SPICE model file? Thank you!
wireless power transfer
Hello experts!my GP is to design an offline DC/DC converter ( LLC ) for cordless home applainces similar to the attached file, now I am aware of how to design LLC for conventional Chargers (wired) to some extent, but i get compeletly confused when i...
Designing High PF AC-DC conveter
We were designing 24v 1.5 Amp smps using l6562 referring application note AN1059 fig 16. getting the 24 output but fluctuating when load is connected and without load power factor is 1.00 and with load it drops down to 0.2 PF and which configuration ...
Rise/Fall Time Issue with STW3N170 in H-Bridge to test High dv/dt test setup for our sensor using driver used UCC21330
I'm using MOSFET STW3N170 in an H-Bridge configuration along with TI’s gate driver UCC21330. During testing, observed an issue with the switching speed as the test is for high dv/dt Observed Behavior: Rise time ≈ 5 µsFall time ≈ 5 µs Test Conditions...
In the SPI protocol of L9305, how is the cnt bit of bit21 used
Hi, There is no specific writing description for the cnt bit in the manual.I guess it's the first time I've powered on and written 1. If I reset the chip through the reset pin, should the cnt be written to 1 after the reset or keep the negation of th...
STP08CP05TTR: Clarification on Using External Current Control for LED Dimming
Hi Sir,We have connected the REXT resistor with a value of 241 Ohms, which sets the current to 80 mA. I would like to confirm whether it is possible to use an external current control circuit to dim the LED.For example, in the case of STP08CP05TTR, w...
