These devices are suitable for factory automation equipment, ECU, BMS systems, portable equipment, and other automotive, industrial and consumer devices.
Traditional low-voltage detectors with an open drain output have a number of drawbacks, such as requiring additional resistors to divide the monitored voltage and pull-up resistors at the output, which can lead to an increase in component count and leakage current concerns.
The SENSE pin of the NV3600 and NV3601 series, however, has a high withstand voltage and has no need for a voltage divider resistor. Furthermore, designers have the option to choose between NMOS open-drain or CMOS output types. Both features effectively eliminate the leakage current issue and do not require additional external components.
For monitoring power supplies that experience large voltage fluctuations, such as those found in automotive batteries or in noisy environments, the NV3600 series allows users to set the detection voltage (VDET) and release voltage (VREL) individually. By selecting the appropriate hysteresis width based on system requirements, it is possible to avoid false detection and misinterpretation, even when the voltage fluctuation is significant.
For reliable system operation and safety, specific systems require monitoring of abnormalities not only when the monitored voltage decreases but also when it increases beyond a certain threshold. The NV3601 series provides window monitoring, enabling simultaneous monitoring of under-voltage and overvoltage with a single chip, saving components on the board.
Both these products are available in consumer, industrial and automotive versions (AEC-Q100 compliant soon). In addition, the IC is embedded in a small SOT-23-5 package measuring only L2.9 x W2.8 x H1.1 mm.
Samples and evaluation boards are available now and can be obtained from our approved local distributors or online partners.
