Ideal for preventing degradation and destruction of ICs and components due to overvoltage caused by peripheral device abnormalities!
The RT8H060C and RT8H070C are ICs that detect overvoltage on power and signal lines. They monitor overvoltage by inputting a signal from a voltage divider of the power and load lines into the IC. When overvoltage is detected, they output a signal to indicate an abnormal condition. Since they have a built-in timer circuit, it is possible to prevent false detection from transient voltage spikes. The output format adopts a latch type, meaning that once overvoltage is detected, the signal indicating an abnormal condition continues to be output even after the overvoltage state is cleared. To reset the abnormal detection state, it is necessary to either recycle the power or input a reset signal to the product, allowing for safe resumption of operation. The voltage value for detecting overvoltage and the timer duration can be set externally for this product, 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.
