The MAX8521ETP+T is a specialized power management IC from Analog Devices, designed to drive thermoelectric coolers (TECs) in compact optical modules. It provides a precise ±1.5A output current, crucial for eliminating harmful current surges and ensuring reliable operation.
This device operates from a wide input voltage range of 3V to 5.5V and features on-chip power MOSFETs, reducing the need for external components. Its high switching frequency minimizes the size of external passive components, making it ideal for space-constrained applications. The MAX8521ETP+T offers accurate, individually adjustable heating and cooling current limits, along with a 2% accurate TEC voltage limit, enhancing the reliability of optical modules.
Packaged in a 20-TQFN (5x5mm) surface-mount form factor, the MAX8521ETP+T is suitable for automated assembly processes. It operates within an industrial temperature range of -40°C to +85°C, ensuring performance in various environmental conditions. The IC also includes features like ripple cancellation for low noise and an analog output to monitor TEC current.
