High Voltage Monitor IC NJU7890 From NJR
NJU7890 Can Directly Detect 1000V With High Precision
New Japan Radio (NJR) has developed a high voltage monitor IC "NJU7890" that can detect DC 1000V voltage.
Small size and high performance have been required for inverters and batteries in eco-friendly cars such as hybrid cars and electric cars. Older solution required often a lot of space in front of the OpAmp.
The new IC NJU7890 offers high input resistance as a one-package solution and high precision. The voltage monitor block with NJU7890 improves the performance of eco-friendly cars and makes them smaller and lighter.
