BTA41-600BRG stuck ON in some cases
We are using BTA41-600BRG triacs on our temperature control boards to turn on 240V tank heaters. The tank heaters are 1500W, 3000W, or 4500W depending on the unit model and operate at 240VAC. The circuit we are using is attached. We use a FOD4108 dri...
TCPP03 compatibility with FETs that have a low Vgs(min)
We are looking at using the TCPP03 and TCPP01 for a system with a dual-role power port and a sink port. We want to use this dual MOSFET with both ICs (a dual MOSFET is needed for the TCPP01 to prevent backflow): https://fscdn.rohm.com/en/products/dat...

L9780 Supporting Firmware
Hello,Does anyone have any firmware for interfacing with the L9780 wideband controller. I am planning on using a LSU 4.9 but any sensor configuration would be useful.Any information is appreciated. Thanks,
Requesting Spice Model for L9338
Hello I’m currently working on a design that uses the L9338 Quad Low-Side Driver and would like to perform circuit simulations in LT spice (or any compatible simulator). Could you please provide the SPICE model for the L9338?If it’s not available pub...
Resolved! STUSB4500 Variable Voltage
Hello, Is there a way to set up the Sink PDO to take in a variable voltage? I would like to set up PDO2 5-20V 3AmpsPDO3 5-20V 5Amps My plan is to use the Power Ok GPIOs to determine how much current I have and do some down stream current limiting. ...
