Power-supply supervision circuits made simpler with DACs
When designers are defining a system-level power supply, one key consideration has to be the addition of the appropriate protection circuits in order to ensure that the design is not only effective, but robust.
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.
