NCT24 Datasheet Low Cost Single Trip Point Temperature Sensor

Manufacturer: onsemi

Overview: NCT22, NCT24 Low Cost Single Trip Point Temperature Sensor The NCT22 and NCT24 are programmable solid state temperature sensors designed to replace mechanical switches in sensing and control applications. Both devices integrate the temperature sensor with a voltage reference and all required detector circuitry. The desired temperature set point is set by the user with a single external resistor. Ambient temperature is sensed and pared to the programmed setpoint. The OUT and OUT outputs are driven to their active state when the measured temperature exceeds the programmed setpoint. The NCT22 has a power supply voltage range of 4.5 V to 18 V while the NCT24 operates over a power supply range of 2.7 V to 4.5 V. Both devices are useable over a temperature range of –40°C to +125°C. Both devices feature low supply current making them suitable for many portable applications. The devices are offered in surface mount packages.

This datasheet includes multiple variants, all published together in a single manufacturer document.
