The ISL6173 from Renesas is a Dual-Low-Voltage Hot Swap Controller that is ideal for distribution and control, power supply sequencing and hot swap/electronic breaker circuit applications. It requires an input voltage of 2.25 – 3.63 V and an input current of 9 mA. This eFuse IC incorporates a charge pump to drive external N-channel MOSFETs. It provides regulated current protection with adjustable duration, ensuring controlled and reliable operation under varying conditions. This eFuse IC offers optional latch-off or retry response modes, allowing users to choose the most suitable operational strategy for their specific requirements. It features an adjustable soft-start mechanism, contributing to a smooth and controlled startup process and preventing excessive inrush currents. This RoHS-compliant eFuse IC is available in a surface-mount package that measures 5 x 5 x 1 mm.
