Using STSPIN220, how to detect torque increase and stall ?

Hi,I'm using STSPIN220 to drive a stepper motor with a pushrod.I only using full step mode, in order to have max. torque.I would like to detect when pushrod gets in contact with some item (increase torque), and also if stall/blocking.what would be th...

MASTERGAN rail-to-rail power supply

Hi,I am wondering if I can use the MASTERGAN with dual power supplies. i.e. high power supply +48V and low power supply -48V. In other words, the Drain of the high side GaN is +48V and Source of the low side is -48V.Regards,Mustafa

Dear Sir, I am using IC L6562A For PFC but i am not able to add mains over voltage protection in this so please give me idea about it....

IC STPM33 is possible to use for measurement: active power, apparent power, RMS value of current and RMS value of voltage. The question: does it measure the RMS value of current in the case, when AC current is not sinusoidal.

The voltage is sinusoidal but the current is after PWM modulation ( dimming of LED lamp)
