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).

Low voltage driven MOSFET

Low voltage driven MOSFET

Expanding the lineup of low-voltage drive MOSFETs!

In mobile devices such as mobile phones, it is necessary to reduce circuit losses in order to decrease power consumption and extend operating time, which has led to a demand for low-voltage driven MOSFETs. As our first initiative, we are expanding our offerings for 1.8V and 1.5V driven products through optimization of the wafer process, and we plan to develop 1.2V in the second phase and 0.9V in the third phase.

1A built-in NPN transistor

1A built-in NPN transistor

Built-in resistance allows for miniaturization of the set and reduction of component count due to the compact surface mount design!

The latch current is large, with a collector current of 1.0A, making it optimal as a driver. The built-in type with a Zener diode has a Zener diode integrated between the collector and base, preventing the transistor itself from being destroyed by back electromotive force during solenoid drives such as motors and relays.

Three-phase bridgeless active filter

Three-phase bridgeless active filter

Customers using the harmonic suppression device (active filter), we have good news!

This product is a so-called PFC circuit (power factor correction circuit). However, our company has changed the circuit configuration from the conventional single-chip active filter method using a diode bridge to a bridge-less active filter method, achieving a power factor of 0.99 or higher, an efficiency of over 96%, and compliance with harmonic regulation (clearing JIS C 61000-3-2). By using this product, a harmonic suppression device will no longer be necessary, so there will be no issues with installation costs or space! Additionally, it is an ideal product for power supply systems that require high power factor and high efficiency. The AC200V input specification is available for sample lending, and the AC400V input specification is also nearing completion for samples. We encourage interested customers to evaluate it! Furthermore, we can also accommodate custom specifications based on this product! Please feel free to contact us through our website.

Power supply (DC/DC)

Power supply (DC/DC)

An explanation of DC/DC converter circuits, which have become common cases integrated with control circuits.

Let me introduce you to "Power Supply (DC/DC)." In recent years, due to the trend towards higher density, it has become common for DC/DC converter circuits to be integrated with control circuits. There is a need to achieve compactness while ensuring heat dissipation, current capacity, and withstand voltage along the surface. Additionally, it is necessary to appropriately handle conflicting elements such as optimizing GND return, minimizing feedback signals, and considering EMC/EMI. *For more details, please refer to the PDF document or feel free to contact us.*
