摘要： Provided are a battery protection IC adaptable to any number of batteries connected in series without increasing a breakdown voltage thereof, and a battery device including the battery protection IC mounted thereon. A charge control signal input terminal and a discharge control signal input terminal of one battery protection IC are provided with a clamp circuit (121), and hence an output driver (112) of another battery protection IC connected to those terminals is not applied with a voltage equal to or higher than a breakdown voltage. Accordingly, the breakdown voltage of the battery protection IC is not required to be high.
摘要翻译：提供一种电池保护IC，其适用于串联连接的任何数量的电池，而不增加其击穿电压，以及包括安装在其上的电池保护IC的电池装置。一个电池保护IC的充电控制信号输入端子和放电控制信号输入端子设置有钳位电路（121），因此与这些端子连接的另一个电池保护IC的输出驱动器（112）不被施加电压等于或高于击穿电压。因此，不需要电池保护IC的击穿电压。

摘要： Provided is a battery pack capable of implementing temperature protection with ease. Regardless of whether or not a battery protection IC (11) has a terminal for temperature protection of a battery pack (10), the battery pack (10) is capable of implementing the temperature protection by using an N type FET (15) and a resistor (17). Accordingly, there is no influence of the presence/absence of the terminal on implementing the temperature protection of the battery pack (10). Therefore, the battery pack (10) may implement the temperature protection with ease.
