BQ24095: Iset programable

Part Number: BQ24095


I want to be able select the output current with program.

I want to connect the Iset1 to PWM with FET so I could switch resistance due to the DC

do you have recommended FET or frequency to work with? 



  • Hi Shai,

    I assume you are going to have 1 or more resistors + series FET in parallel and switch in different equivalent resistor values for ISET1.  If so, then any low cost NFET should work, as long as it Vth is below your MCU GPIO drive voltage.  Regarding frequency, the current regulation loop has a finite response time in the 1ms range.  I suggest not switching faster than that in order to give the current loop time to settle.
