Ideal for preventing degradation or destruction of ICs and components from overcurrent during load short circuits and overvoltage due to abnormalities in surrounding devices!
The 『RT8H020C』 is an IC that detects two abnormal conditions: overcurrent and overvoltage on the power and load lines. The overcurrent detection function monitors the voltage across a current sensing resistor connected externally to the IC, allowing it to detect overcurrent conditions. The detection circuit includes hysteresis to prevent false detection. The overvoltage detection function monitors the voltage of the target by using a resistor divider to scale down the voltage. The output is an OR output of the overcurrent detection signal and the overvoltage detection signal, which means that if either abnormal condition is detected, it will output a signal (Low) to indicate the abnormality. Additionally, the output format is open collector, allowing for input to different power systems (level shifting). The detection values for overcurrent and overvoltage can be set using resistors connected externally to the IC, 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.
