Driver Recommendations for Nextreme Modules
Download Application Note

Nextreme’s product portfolio includes modules that range in resistance from 50mΩ to 3Ω with corresponding Imax currents of 0.8A through 4A. The optimal drive current for these modules in an application is likely to be in the 0.2A to 1.5A range. Several off-the-shelf Thermoelectric Cooler Controllers or Temperature Controllers are available to drive and control Nextreme modules.

Cold-Side Temperature Sensing on Thin-Film TE Coolers
Download Application Note

Integrated temperature sensing of the cold-side of thin-film thermoelectric coolers is a challenge due to small surface area of the coolers’ top header. Micro-scale thermistors can be mounted either directly onto the top surface of the header or on the side of the top header to enable closed-loop temperature control.
