Ptc short circuit protection
WebOver-current protection is normally provided by a current sensing device which detects when the upper current limit of the battery has been reached and interrupts the circuit. Since current is difficult to measure the usual method of current sensing is by measuring the voltage across a low ohmic value, high precision, series, sense resistor in ... WebThe protection circuit incorporates inrush current control using P-MOSFET, a series diode to block the reverse current as well as reverse polarity, a fuse for overload or short-circuit …
