Product Overview
The MAX8521ETP+T is a smallest TEC power driver for optical modules in 20 pin TQFN package. It is designed to drive thermo electric coolers (TECs) in space constrained optical modules. It delivers ±1.5A output current and control the TEC current to eliminate harmful current surges. On-chip FETs minimize external components and high switching frequency reduces size of external components. It operates from a single supply and bias TEC between 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 set-point is very close to natural operating point, requiring small amount of heating or cooling. An analogue control signal precisely sets TEC current.
- Supply voltage range is 3V to 5.5V
- Operating temperature range from -40°C to +85°C
- Low profile design, on-chip power MOSFETs
- High efficiency switch mode design
- Ripple cancellation for low noise, ITEC monitors TEC current
- Direct current control prevents TEC current surges
- 5% accurate adjustable heating/cooling current limits
- 2% accurate TEC voltage limit, 1% accurate voltage reference
- No dead zone or hunting at low output current
- Switching frequency up to 1MHz, synchronization
