Posted on June 25, 2018 at 03:34Now I try to control the BLDC motor with ICS.There is no example for ICS. : DAsk the STM Forum members.SpecificationsMCU: STM32F427VGIPM: STGIB15CH60TS-LCurrent Sensing IC: AMC1200 (FDA) (Isolation)Motor current phase...

LED2000DR led driver mcu in which i functioned the circuit for 1.4 Amps. But i got the output only 0.3 Amps only. Output voltage is still 5v But current is very less.

Hi Friends,I have designed a circuit using LED2000DR for a project. I given 5V input to the circuit and i got 5V same as given in the input. The circuit i designed for 1.4 Amps But i got the 0.3Amps only. I am confused that why the current is low. Bu...
