Power-supply supervision circuits made simpler with DACs

Although achieving system-level voltage and current protection can add complexity to your design, you can attain a solution with minimal compromise and cost by incorporating small, cost-effective digital-to-analog converters (DACs) plus simple window comparators.

TI’s 10-bit DAC53608 precision DAC, first in a new family of small, cost-effective voltage output DACs, offers just such a solution to this design challenge.

Power-supply supervision is a circuit required in almost all power-supply applications that use shared supply rails across multiple boards or modules. This circuit, while necessary for the protection of system-level components in case of a fault, is often perceived as adding design complexity and cost. 

Therefore, implementing a robust power-supply supervision circuit cost-effectively becomes one of the key challenges for any designer. Common applications requiring such supervision circuits include communications equipment, battery test systems and automated test equipment.
