VREG on L9963E chip
Hi, I see on the datasheet that the external NMOS on the voltage regulator is connected to the positive terminal of the battery stack. Since the VREG voltage is 6.5V, can I connect the external mosfet to a lower tap of the battery stack? I want to do...
asking about steval-1sa170v1
Hello, where can i find the altium files for steval-1sa170v1?
Resolved! I am Finding wireless charging guru ▶ Heat comes out while Wireless charging.
Hello everyone !I am using STWBC86 and STWLC38 MCUs, using our own custom board.The wireless charging was going well, but the problem is this.[ When charging → put away the RX → put back the RX ] ...▶ the heat comes out from the RX MCU.Any ideas to s...
SiC MOSFET die datasheet and electrical simulation model
Hello,We are evaluating the performance of SiC MOSFET bare die with SiC MOSFET module.Can you share the detailed datasheet and simulation model of SiC MOSFET bare die?Thanks in advance.-BR,Rushi
STC3115 Vcc Pin Getting ~0.7V In Power OFF
Hi Team,I'm using STC3115AIQT on one of my projects for a 3.7V Li-Ion battery monitoring. I'm powering the IC by supplying an external 3.3V on the VCC pin (From an LDO) of the IC and giving my battery voltage input on the VIN pin.During the normal op...
Resolved! Backup power
Hello, my device will work in a car and I need to arrange power for the RTC. Is the H750 processor used, is the diagram in the screenshot suitable or are there better technological solutions?
Isolation between NC pin and Cathode on STPSC20H12-Y
We have an application using an STPSC20H12-Y silicon carbide power Schottky diode in the D²PAK HV package (full MPN STPSC20H12G2Y-TR). This diode has a No Connect pin that we would like to tie to the Anode pin to simplify board layout and improve th...
Bias voltage on ST1L08PUR
Little confused by the spec of a max 90mV dropout while the Bias voltage needs to be >=1.5V higher than the regulated voltage.So this regulator is only good in the case where that higher voltage is already present in the system?https://www.st.com/con...
drive & dimm 72 leds + 72 leds all in same accurate and controlled current.
hi, i need to drive & dimm 72 leds (vf=3.2v ;0.35A) + 72 leds (vf=2.2v; 0.3A). i want to use low Vin such as 24-48Vmax There are so many combinations.What is the simplest and cost effective way, for a simple drive and dimmer (by MCU). i want to drive...
How to tune FOD parameters on the STWBC IC.
I'm using the STWBC as the IC to control the transmitter of a wireless battery charger. So far the battery is charging fine but I am unable to get foreign object detection working. I am adjusting the FOD parameters using the STWBC GUI application. Is...
