Timer latch function built-in overcurrent detection IC 'RT8H010C'

Timer latch function built-in overcurrent detection IC 'RT8H010C'

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.

TVS (for USB2.0 to USB4 applications)

TVS (for USB2.0 to USB4 applications)

Choosing the appropriate TVS (Transient Voltage Suppressor) protects the product from latch-up.

With the development and improvement of USB interfaces and protocols, many smart products are adopting USB Type-C as their connection interface. This allows for the support of diverse video, audio, and data transmission at higher transfer speeds. At the same time, signal transmission has become more susceptible to interference from external power surges. Therefore, the use of TVS diodes for surge protection should be more stringent. However, if users pursue only TVS devices with low clamp voltages without considering other parameters such as operating voltage, there is a risk of affecting real-time communication on the Type-C interface or, in extreme cases, causing latch-up due to EOS (electrical overload), which could damage the circuit. To achieve proper and effective transient voltage surge protection in the interfaces of electronic products with complex signal and power lines, adding TVS diodes to the interface will be the most effective protection solution.
