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.

Overcurrent and Overvoltage Detection IC "RT8H020C"

Overcurrent and Overvoltage Detection IC "RT8H020C"

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.

Overvoltage detection IC with built-in timer latch function 'RT8H060/070C'

Overvoltage detection IC with built-in timer latch function 'RT8H060/070C'

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.

2ch window comparator "RT8H171E"

2ch window comparator "RT8H171E"

Ideal for bulk voltage monitoring and sensor signal processing with a 2ch window comparator!

This product incorporates two window comparator circuits. It outputs high (H) when the input signal (VS) is within the range of two reference voltages (VIN1 & VIN2) that can be determined externally. The output of each comparator is an open collector output, allowing for level shifting using any power supply. With this single product, you can monitor two systems for voltage drop and overvoltage simultaneously, as well as process sensor signals. Additionally, compared to the RT8H151C, which has one built-in window comparator circuit, this product has a wider power supply voltage range, making it usable even when the power supply voltage is high (17V to 36V).

Power Supply Voltage Monitoring IC 'RT8H182E'

Power Supply Voltage Monitoring IC 'RT8H182E'

Monitor voltage drop in the 2 systems! Additional overvoltage monitoring circuit can also be added!

RT8H182E is a power supply voltage monitoring IC that detects power supply voltage interruptions or drops and generates a reset signal (L output). It can monitor two power supply systems, including the power supply voltage. The monitoring voltage for the power supply voltage can be changed by external resistors. The detection voltage for the other power supply voltage can be adjusted using a resistor divider. It is also possible to set the delay time for reset release using an external capacitor. Additionally, this product has one built-in comparator. Since this comparator has an open-collector output, level shifting using any power supply is possible. By inputting the power supply voltage using a resistor divider, it can also be used for overvoltage detection. By connecting the reset output terminal to the input terminal of this comparator, it can also be used for logical inversion of the reset output.
