Why am I killing NFET on low side of motor drive?

I am using an STS10N3LH5 on the low side of a half bridge circuit. I have a schottky diode across the motor. For lighting applications we PWM the ground and everything is fine. However, during motor applications we PWM the high side and will somet...

Li-ion battery charger.

I want to design a Li-ion battery charger.Q1. How charge will know that it should work in constant current or constant voltage mode?Q2. How same charger can be configured for constant voltage and constant current operation?Regards,Vivek

BTA16-600BW not turning off

HiI have been testing the following circuit (which apparently works). I am finding that the TRIAC (BTA16-600BW) does not turn off with an inductive load (induction motor at 240V, 3A. 50Hz) yet with a simple house lamp the circuit works switching the ...

Where do I find more detailed information on the STWBC Qi GUI used with the STEVAL-ISB044V1 Wireless Power Ref Design? How to interpret FOD metrics.

Hello, I recently started using the STEVAL-ISB044V1 Wireless Power Ref Design and it looks really useful. I am trying to figure out how to interpret some of the data in the FOD Metrics GUI. For example, if it click on the "Snapshot FOD internal metri...

What am I doing wrong with the l6470 stepper driver?

We develop electronics for controlling multiple stepper motors and use the L6470 as drivers. Radiators with fan cooling mounted on the chip of the driver (above). The current does not exceed 2 amperes. Radiators remain cold.The problem is that driver...

Power Consumption during the use of Bluetooth and ways to reduce it?

Is there any specs out there that details the power consumption during the use of bluetooth, like in run mode? and is there any to reduce it to save power without heavily affecting the performance of the device?

LED2001 LED DRIVER. I wonder if Schottky diode should be added in the circuit. Typical application circuit in the data sheet does not include the external diode. Is the diode built in the LED2001 chip?
