Dual Trip Temperature Switch IC S-5842A Series

The S-5842A Series is a dual trip temperature switch IC which detects two points of temperature. The S-5842A Series operates with a low supply voltage down to 2.5 V, and it has low current consumption of 10 µA typical. The S-5842A Series consists of a negative coefficient temperature sensor, a reference voltage generation circuit, and a comparator integrated in a single IC. The package options are the SNT-6A and SOT-23-6.
