高精度过电流保护
eFuse IC的过电流保护功能是指当输出电流因异常负载或短路而增加时，夹紧（保持）输出电流以防止其超过过电流限制（ILIMIT）的功能，从而防止瞬时断电，保护装置免于因发热而退化或损坏。东芝eFuse集成电路可以通过使用外部电阻的可变过电流保护功能进行最佳设置。除了当输出电流在极短时间内大大超过极限电流时可以开启短路保护功能外，还可以通过双过电流保护功能实现强有力的保护。
我们的eFuse IC TCKE8系列具有从低温到高温的高精度过电流钳位限制功能。正常过电流保护功能（断路器）将在达到过电流极限时立即停止输出电流，输出电压下降。另一方面，eFuse IC将钳制电流，防止其流动超过设定电流。将输出电压控制在后级集成电路的击穿电压范围内，可以构造出更稳定的电源。
