    摘要： There is provided a method of correcting an overcurrent detection voltage of a battery protection integrated circuit including a current path between a first terminal and a second terminal, one or more transistors for controlling current of a secondary battery, an overcurrent detection circuit and a control circuit. The method comprises the steps of: measuring a resistance value between the first terminal and the second terminal wherein the one or more transistors are turned on at a predetermined temperature; estimating resistance values between the first terminal and the second terminal at respective temperatures based on the measured resistance value; calculating adjusting data for canceling temperature dependency of charge or discharge current of the secondary battery based on the measured resistance value and the estimated resistance values, wherein a value of the charge or discharge current varies depending on temperature; correcting the overcurrent detection voltage based on the calculated adjusting data.

    摘要： A battery protection IC has detection circuits to detect faults of an overcharge, an over-discharge, and an overcurrent of a secondary battery; a control circuit to protect the secondary battery, by controlling (dis)charging the secondary battery upon the fault; and a delay circuit to generate delay after the fault before the controlling. The IC includes a memory unit to store data for setting and adjusting a circuit characteristic of the IC; and a setting circuit to set and adjust the circuit characteristic, based on the data from the memory unit. The memory unit includes a pair of non-volatile memory cells to complementarily store one bit, and a latch circuit directly cross-coupled with the memory cells, for each bit of the data. The latch circuit statically outputs the data from the memory cells to the setting circuit when the IC is turned on.
