Operating from a 3V to 5.5V supply rail, it integrates the power stage and control logic needed to drive a TEC in both heating and cooling directions without external H-bridge FETs. ## Package and board integration Housed in a 36-WLP (Wafer-Level Package) measuring 3.07mm x 3.07mm, the MAX8521EWX+T mounts directly on the PCB with a surface-mount reflow profile — no leadframe, no mold compound, just the silicon die with solder bumps. The WLP footprint demands a clean solder-paste stencil and a controlled reflow oven; the bump pitch and pad layout are optimized for the 36-ball array, and the package's low profile suits tight optical-bench assemblies.","metaTitle":"MAX8521EWX+T Analog Devices TEC Driver, 36-WLP","metaDescription":"MAX8521EWX+T Thermoelectric Cooler driver IC from Analog Devices.
