ROHM’s 40V Window-Type Voltage Detector: Providing High Accuracy and Ultra-Low Consumption

ROHM developed the high accuracy, ultra-low current consumption voltage detector (reset IC) BD48HW0G-C. It 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.

The new BD48HW0G-C window-type voltage detector utilizes high-voltage BiCDMOS processes along with ROHM’s proprietary analog design technology. The aim: enabling operating voltages up to 40V 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 leveraging ROHM’s proprietary ultra-low current consumption technology Nano Energy™. It reduces current consumption to just 500nA (0.5μA, only 6% of standard products with equivalent functionality and accuracy, more info).
