The MAX8521EWX+T is a specialized power management integrated circuit designed by Analog Devices / Maxim Integrated for driving thermoelectric coolers (TECs) in space-constrained optical modules. This device delivers a precise ±1.5A output current, effectively controlling TEC current to prevent harmful surges. It operates from a single 3V to 5.5V supply.
Key features include individually adjustable heating and cooling current limits with 5% accuracy, and a 2% accurate TEC voltage limit, enhancing the reliability of optical modules. The device also monitors TEC current via an analog output signal and incorporates a ripple cancellation scheme for reduced noise. The MAX8521EWX+T is available in a 36-WLP (3.07x3.07) package, suitable for surface mounting.
This IC is ideal for applications such as SFF/SFP modules, fiber optic laser modules, and fiber optic network equipment. Its high-efficiency switch-mode design and on-chip power MOSFETs minimize external component count and reduce overall solution size. The switching frequency can be pin-selected between 500kHz or 1MHz, offering design flexibility.
