MASTERGAN1TR failing and smoking at 100VDC
We are using 2 MASTERGAN1TR to drive current across an inductor.We are seeing damage on the body of the chip nearest the low side ground connection with a PWM Frequency of 250KHz and a 12% duty cycle.Before the chip fully fails the current decreases ...
Issues with VNQ9080AJTR Quad-Channel high-side driver Output and Input Behavior.
Hello STM Community, I'm currently working with the VNQ9080AJTR Quad Channel High-Side Driver, and I'm encountering a couple of issues that I hope someone here can help me resolve 1.Output Voltage Regulation: With a constant VCC supply of 12V, the ou...
VNQ9080 to controll auxiliary lights of my motorcycle
Hi all. I've made a dedicated PCB that should control auxiliary lights of my motorcycle. I use CANBUS information by MCP2515 module and using Arduino Nano digital output pins to directly control input pins of VNQ9080. I assembled all elements on the ...

About High Side Driver Selection
Hello everyone,I am finding to drive for 4 cabin lock. For this, VNxxx or VNQxxx series help me. I don't need high current. It is 1 amper per channel(per output. I'm looking for a chip that will not cause any supply problems and will be produced con...
powerStep01 Active Position Tracking
Is there a way to read the motor position while it's moving, such as with a command like "run," "goto," "move," or any other command from the Powerstep01? Does the motor need to be stopped for the motor position to be read correctly? Currently, when ...
Mystery IC number ?
Hello allI don't know if this is the right sub-forum, I chose the one that seemed the closest.I've been spending a bunch of time trying to find the part number of a seemingly simple IC, but just hitting walls. I've Googled using the manufacturers nam...
L9916 Programming Mode
We are evaluating the L9916 IC and need to test it with different settings. We are following the information in the Datasheet and the Programming App Note. We keep the IGN, PHASE and LAMP pins at 0V right until the moment we send the ignition sequenc...
Precision voltage reference with low 1/f noise
Hi all, I am looking for two voltage references to produce two rails ( positive and negative) with low frequency noise.The voltage reference does not need to have a tight output voltage accuracy and long term precision. It needs to be stable over a 1...
LM317 adjustable voltage setting question
I'm reviewing the datasheet for the LM317 linear regulator, and it lists the equation for calculating voltage as:VO = VREF (1 + R2/R1) + IADJ R2If I plug in the numbers from my circuit (and neglect the error calculation), I get:1.25 * (1+(1400/400)) ...
