Solid State Temperature Sensors
Both devices also feature programmable temperature set points, ± 2 ° C hysteresis, and fire/heat detection. The NCT22's supply voltage range is 4.5 V to 18.0 V, while the NCT24 has a 2.7 V to 4.5 V voltage range. Each device comes in a standard 8-Pin SOIC package and have a low current supply for longer battery life. Applications include CPU thermal management in personal computers and amplifiers.
