Solving various voltage monitoring challenges for automotive and industrial equipment.
The "N V3600" and "NV3601" series are voltage detector ICs for automotive and industrial equipment, allowing for individual setting of detection voltage and release voltage, with a hysteresis width that can be set over a wider range than conventional models, and capable of simultaneously monitoring low voltage and overvoltage.
A light load mode that operates at 30mW or less! An ideal control IC for future AC/DC power supplies.
The NJW4790 is a self-oscillating switching power supply control IC used in isolated flyback power supplies employing the pseudo-resonant RCC (Ringing Choke Converter) method. It eliminates the disadvantages of the RCC method, achieving high efficiency and low standby power consumption. It is suitable for various AC/DC power supplies (AC adapters, residential equipment, industrial equipment, communication devices, etc.) up to around 50W. 【Features】 ■ RCC (Ringing Choke Converter) method - Power is accumulated in the transformer while the switching element is in the on state - The energy stored is released to the secondary side during the off period ■ Pseudo-resonance - Reduces switching losses, achieving high efficiency and low emissions (EMI) *For more details, please refer to the PDF materials or feel free to contact us.

We will help improve the competitiveness of your lithium-ion battery applications with high precision, low consumption, and space-saving solutions.
Applications equipped with 2-cell lithium-ion batteries have primarily included digital cameras, portable DVDs, tablet PCs, intercoms, etc. However, recently, they have also been increasingly used in electric assist bicycles, beauty and health devices, toys, small electric tools, and cleaners. While smartphones have mostly used 1-cell batteries until now, the demand for high capacity and fast charging has led to the emergence of 2-cell models. The "NB7200 series" features industry-leading high-precision overcharge, over-discharge, and discharge overcurrent detection monitors for 2-cell applications. Additionally, by using external resistors, it improves current detection accuracy and adopts a compact DFN1616-8 package (1.6×1.6×0.4mm), contributing to high precision, low power consumption, and space-saving, thereby enhancing the competitiveness of customers' lithium-ion battery applications.
Contribute to improving safety.
The NB7140 series is equipped with industry-leading high-precision overcharge, over-discharge, and discharge overcurrent detection functions for single-cell applications, as well as a forced standby function. Additionally, it has improved the flexibility of the voltage setting for prohibiting charging of 0V batteries (low-voltage batteries). Furthermore, the NB7140 series features a forced reset function, while the NB7141 series is the world's first single-cell protection IC to include a watchdog timer function. This enhances safety, contributes to high precision, low power consumption, improved safety, and space-saving, thereby enhancing the competitiveness of our customers' lithium-ion battery applications.
High-side protection IC with temperature protection function for 1-cell lithium-ion batteries "NB7120 Series"
The NB7120 series from Nisshinbo Micro Devices is a high-side N-channel MOSFET drive type that facilitates communication by preventing differences in ground levels between the system side and the battery pack side. By enhancing the overcharge detection accuracy (from -20°C to 60°C) and the charge/discharge overcurrent detection accuracy to industry-leading levels, it improves the safety of the equipment. Additionally, by stopping the internal circuit, it minimizes the current consumption after over-discharge detection, which helps to reduce the depletion of battery capacity during inventory periods before product sales.
