Ideal for preventing degradation or destruction of ICs and components from overcurrent such as load short circuits!
The "RT8H010C" is an IC that detects overcurrent in power and load lines. By inserting a current sensing resistor in the power and load lines, it monitors overcurrent based on the voltage difference across the resistor. When overcurrent is detected, it outputs a signal (High signal) to indicate an abnormal condition. It has a built-in timer circuit, which prevents false detection of inrush currents during power-up. The output format adopts a latch type, meaning that once overcurrent is detected, it will continue to output the abnormal signal even if the overcurrent condition is removed. To clear the abnormal detection state, it is necessary to either reset the power or input a reset signal to the product, allowing for a safe resumption of operation. The current value for detecting overcurrent and the timer duration can be set externally, allowing for flexible configuration according to the customer's circuit conditions.

Company information
Isahaya Electronics began production of small signal transistors in 1973 and has evolved its semiconductor technology into design technologies for gate drivers and DC/DC converters. In recent years, the company has also focused on developing high-efficiency, high-power-factor power supply technologies to contribute to carbon neutrality. (Three-phase PFC, 1500V input compatible DC/DC converters, bidirectional converters, etc.) Meanwhile, to meet diverse needs, small signal transistors have also evolved with enhanced functionality and integration, expanding the lineup of high-voltage, high-current transistors, MOSFETs, and analog ICs.
