L6398 Problem
Hello my Friends.Please help me.I got a problem with L6398 for bldc driver.the above picture is 1 phase for bldc driver using L6398 and FR3607. After I got PCB and soldered it. But when I tested it, I got the problem as:Here is the truth table of L63...
VNH7040AY can't start 120W brush motor
We use VNH7040AY to drive a 120W brush motor(23v-29v), however, can't start, need to remove the load, or reduce the load. we have also done such as soft-start, connect in series NTC(4R) to start, not getting very good improvement. Could you give us s...

VNQ500 burns out
Hello, We are using the VNQ500 in our board to drive loads at 24V. While testing our board the VNQ500 causes troubles and we noticed high voltage going back to the inputs of the MCU. Our schematic is pretty simple: VCC, CE and EP are all connected to...
VNH5050 diag pins and pwm input
I am designing a quad motor controller using 4 vnh5050. The motors will be controlled independently through INA1 - INA4 & INB1 and INB4 signals from uC.In order to keep pin count usage down:1) Can I connect the DIAGA and A DIAGB pins together and ...
