２次保護ＩＣ、２次保護ＩＣの制御方法、保護モジュール、及び電池パック
Document Type and Number:
Japanese Patent JP6530586
Kind Code:
B2
Abstract:
A secondary protection IC is connected in parallel with a rechargeable battery and controls the charge and discharge of the rechargeable battery separately from a primary protection IC. The secondary protection IC includes a detection circuit that detects an overcharge or overdischarge of the rechargeable battery, a regulator that stabilizes the voltage of the rechargeable battery and outputs the stabilized voltage to the outside of the rechargeable battery, and a control terminal that controls the regulator with a control signal. Each of the detection circuit and the regulator performs a normal operation or stops operating based on the voltage of the rechargeable battery and the control signal.
