咨询BQ24630使用TTC脚控制充电时间设置

大家好，咨询BQ24630使用TTC脚控制充电时间设置，在使用外部节点电容的时候，(range from 0.047 μF to 0.47 μF to give 1-h to 10-h safety timer) 最小是否只能设置到1小时，最长只能充10小时。我需要充20个小时后再保护，继续使用20*0.047为最佳电容值吗？直接接上拉5V是永远不进入充电时间保护状态吗？

    您好，请参考TTC的引脚描述，
    Safety Timer and termination control. Connect a capacitor from this node to GND to set the timer. When this input is LOW, the
    timer and termination are disabled. When this input is HIGH, the timer is disabled but termination is allowed
