Supporting Information



The BD48HW0G-C window-type voltage detector features a wide operating voltage range from 1.8V to 40V and an industry-leading detection voltage accuracy of ±0.75% (over the entire temperature range). In addition to a maximum operating voltage of 40V, the detection voltage can be freely set, enabling high accuracy monitoring of abnormal voltages in a variety of applications, at both low and high voltages, contributing to high reliability systems that maximize efficiency in automotive and industrial power supplies. The BD48HW0G-C achieves an ultra-low current consumption of 500nA by ROHM’s ultra-low current consumption technology Nano Energy™. This is only 6% of standard products with equivalent functions and accuracy, making it suitable for applications where increased power consumption is a concern.

Application Examples

  • ◇ Automotive systems: Inverters in EVs/HEVs, electronic control units, ADAS, In-Vehicle Infotainment
  • ◇ Industrial equipment: factory automation equipment, measurement instruments, sensor systems and further automotive and industrial applications requiring voltage monitoring.
