Voltage monitor is optimised for functional safety equipment  

For a range of automotive and industrial applications requiring voltage monitoring of electronic circuits for increased safety, Rohm Semiconductor has developed the  BD48HW0G-C window type voltage detector.

The low current consumption voltage detector (reset IC) can be used in automotive electronic control units and factory automation equipment

The BD48HW0G-C window-type voltage detector uses high voltage BiCDMOS processes with Rohm’s proprietary analogue design technology. It enables operating voltages up to 40V and what is claimed to be an industry-leading detection voltage accuracy of ±0.75 per cent. The detection voltage can be set to monitor abnormal voltages from low to high voltage to minimise fault events, added Rohm.

The BD48HW0G-C leverages Rohm’s proprietary low current consumption technology Nano Energy. It reduces current consumption to just 500nA (0.5 microA, only six per cent of standard products with equivalent functionality and accuracy). 

Samples are available now, and the BD48HW0G-C will be in mass production in October 2022.

Rohm Semiconductor develops and manufactures a large product range including SiC diodes and MOSFETs, analogue ICs such as gate drivers and power management ICs (PMICs) to power transistors and diodes to passive components. Production takes place in manufacturing plants in Japan, Germany, Korea, Malaysia, Thailand, the Philippines, and China. 

Rohm Semiconductor Europe has its head office near Dusseldorf, Germany serving the EMEA region (Europe, Middle East and Africa).
