MAX8521 Overview
Key Specifications
Mount Type: Surface Mount
Max Operating Temp: 85 °C
Min Operating Temp: -40 °C
Description
The MAX8520/MAX8521 are designed to drive thermoelectric coolers (TECs) in space-constrained optical modules. Both devices deliver ±1.5A output current and control the TEC current to eliminate harmful current surges.
Key Features
- An analog output signal monitors the TEC current
- A unique ripple cancellation scheme helps reduce noise
- The MAX8520 is available in a 5mm x 5mm thin QFN package and its switching frequency is adjustable up to 1MHz through an external resistor
