  • RE: BQ25756: the charge and discharge current during constant current mode

    meme wang 说： Could you clarify which pin is used to set this certain current value? The ICHG pin is used to set pre-charge, ICHG, and the termination current. For a capacitor, you'll want to set EN_TERM=0 and EN_PRECHG=0 to disable termination and precharge…

  • why can't a mosfet be directly driven by a microcontroller?

    First, microcontroller I/O ports have limited load capacity, typically allowing currents around 10-20 mA. Therefore, they are generally not used to drive loads directly. Let's briefly compare the differences in driving BJTs and MOSFETs. Bipolar…
