signal.

This means the IPD family can protect the system against both inrush and steady state overcurrent, ensuring greater system safety by providing a high reliability solution with fewer parts compared to conventional products. In addition, the overcurrent protection range can be adjusted with external components to enable broad compatibility. Once an overcurrent condition of the steady state current is detected, the IPD output is controlled (ON/OFF) by the MCU Enable signal.

The devices enable adjustment of the inrush protection time and abnormal current threshold of the steady state current by simply changing the external capacitor and resistor constants, ensuring support for a wide range of systems. This makes it possible to eliminate up to 7 external parts compared to conventional solutions, decreasing mounting area by as much as 70 percent.
