Low power 40-V window-type voltage detector delivers high accuracy
The BD48HW0G-C high accuracy, ultra-low current consumption voltage detector (reset IC) from ROHM is optimized for a wide range of automotive and industrial applications requiring voltage monitoring of electronic circuits for increased safety – including automotive electronic control units and factory automation equipment.
In recent years, continuing technological innovation in the automotive and industrial equipment sectors towards automation has spurred demand for greater safety. Along with this, to build safer systems, product development that takes into account safety guarantees (fail-safe and functional safety) in the event of an incident is required.
To date, ROHM has developed more than 1,000 voltage detectors which play an important role in ensuring the safety of equipment. With a comprehensive product lineup, ROHM ships over 250 million pieces annually (in FY2021) for a wide range of low voltage applications worldwide.
The BD48HW0G-C window-type voltage detector utilizes high-voltage BiCDMOS processes along with proprietary analog design technology developed by ROHM. The result delivers operating voltages up to 40-V and an industry-leading detection voltage accuracy of ±0.75%. At the same time, the detection voltage can be freely set, enabling high accuracy monitoring of abnormal voltages in a wide range of applications, from low voltage to high voltage, contributing to highly reliable systems with minimal incorrect fault events.
In addition, the BD48HW0G-C is leverages proprietary ultra-low current consumption technology, designated Nano Energy™. This reduces current consumption to just 500 nA (0.5 µA), enabling use without worrying about increased power consumption in automotive systems powered by a battery when the engine is stopped. This also makes it suitable for voltage monitoring in various power supply circuits in automotive and industrial applications requiring functional safety.
Going forward, ROHM plans to expand its lineup of high voltage single-type voltage detectors with fixed detection voltage equipped with Nano Energy™ technology to provide greater safety in automotive and industrial environments.
