Q1. How to calculate IGBT gate resistance.I want to use STGD18N40LZ IGBT for operating an inductive switching load. Switching freq:- Between 400Hz to 1KhzCollector to Emitter voltage:- 24V.Avg Max current :- 5A.Q2. What will be impact If I use 1Kohm ...
In the datasheet, it gives a formula, R = (Vi(min)-Vxx -Vdrop(max)) / (IO(max)+Id(max))My IO is 0.1A, My output voltage is 5V. My input is currently 24V. I saw some discussion that I think I should consider the Vdrop to be 7V. Is Vxx the voltage I...
Can we connect SENSEA/SENSEB pins to microcontroller ADC inputs to monitor the current in real time?
We are using ST's LED1202 - 12-Channel LED Driver in our hardware. Which is connected with MPU using I2C. But i am not able to find any HAL Library to drive this IC. ST is providing only binary firmware which works with Nucleo board [here].Please he...
We noticed that there are pulses at the gate drive outputs (pins 15 HVG, & 11 LVG) during the ramp-up of the control voltage (pin 12 VCC).This is what we saw: when VCC reaches about 11V, a sequence of pulses appear on both LVG and HVG. First LVG went...
Question 1:In our circuit Pin 5 STBY is pulled down to 0V to instantly stop pulses on gate drives. But sometimes when STBY=0V we still see pulses at the gate driver outputs LVG, HVG. The datasheet does not mention that gate pulses may still happen.I ...
Dear All,I would like to ask for your help in the following topic. I've got a new task to develop a special balancer to lift up different weights (from 20 to 50kg) without the need of changing it's spring force. The weight of the products has to be m...
