MAX8521ETP General Description
A. General
The MAX8521 is designed to drive thermo-electric coolers (TECs) in space-constrained optical modules. The device delivers ±1.5A output current and controls the TEC current to eliminate harmful current surges. On-chip FETs minimize external components and high switching frequency reduces the size of external components.
The MAX8521 operates from a single supply and bias the TEC between the outputs of two synchronous buck regulators. This operation allows for temperature control without "dead zones" or other nonlinearities at low current. This arrangement ensures that the control system does not hunt when the set point is very close to the natural operating point, requiring a small amount of heating or cooling. An analog control signal precisely sets the TEC current.
The device features accurate, individually adjustable heating current limit and cooling current limit, along with aximum TEC voltage limit to improve the reliability of optical modules. An analog output signal monitors the TEC current. A unique ripple cancellation scheme helps reduce noise.
The MAX8521 is also available in a 5mm x 5mm thin QFN, as well as a space-saving 3mm x 3mm UCSP™, with a pin-selectable switching frequency of 500kHz or 1MHz.
