Power management

VNH7040AY，The 15 pins（sel0） of the chip have a voltage of about 7V, This is obviously abnormal，What might be the problem？ best wishes to you thanks

Need HAL Driver to drive ST's LED1202 - 12-Channel Current LED Driver

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...

L6599AT gate drive pulses appear unexpectedly

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...

L6599AT Questions Q1: STBY pin does not stop pulses on gate drive outputs. Q2: Datasheet confusion for: (a) Soft-Start, (b) LINE.

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 ...

Request for help with a smart balancer development.

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...
