Haechitech – Temperature-sensing for many applications

Haechitech expands their temperature sensing portfolio with more ICs. In addition to the recently launched MXH1310 and MXH1320 they now also started the production of the MXH1330. Each of them for a specific direction.

These products have a market standard package and pin map and since the shortage issues also affect the temperature sensor market, they can replace nearly any competitor product.



The MXH1310 is focused on its 5V operating voltage so it works for most industry standards. For low voltage applications (~2V) Haechitech offers the MXH1320 and MXH1330.  While the MXH1320 focuses on its low power consumption, so it is ideal for any Neue Temperatursensoren MXH13xxbattery-powered products. The last one, the MXH1330, features a very small package, so it can fit in almost any design.
