Description

The AL5812 is an adjustable Linear °C driver offering excellent temperature stability and output handling capability. The AL5812 simplifies the design of linear and isolated or non-isolated °C drivers by setting the °C current with standard value resistors. The AL5812 has an open drain output that can swing from 1V up to 60V enabling it drive long °C chains. Its low 0.5V RSET pin is outside of the °C current path and so accuracy is maintained while minimizing the required overheads to regulate the °C current. This reduces its power dissipation when compared to traditional linear °C drivers. This makes it ideal for driving °Cs up to 150mA (commonly referred to as μW °Cs). Longer °C chains can be driven by tapping VCC from the chain, where the chain voltage may exceed 60V. The AL5812 is available in the exposed pad MSOP-8EP and U-DFN3030-6 packages.
