The MAX16063 is a 1% accurate, adjustable, quad window voltage detector in a small thin QFN package. This device is designed to provide a higher level of system reliability by monitoring multiple supply voltages and providing a fault signal when any of the voltages exceed their overvoltage thresholds or fall below their undervoltage thresholds.
The MAX16063 offers user-adjustable voltage thresholds that allow voltages to be monitored down to 0.4V. This allows the upper and lower trip thresholds of each window detector to be set externally with the use of three external resistors.
Each monitored threshold has an independent open-drain output for signaling a fault condition. The outputs can be wire-ORed together to provide a single fault output. The open-drain outputs are internally pulled up with a 30µA current, but can be externally driven to other voltage levels for interfacing to other logic levels.
Features include a margin input to disable the outputs during margin testing or any other time after power-up operations. Also featured is a reset output that deasserts after a reset timeout period after all voltages are within their threshold specifications. The reset timeout is internally set to 140ms (min), but can be externally adjusted to other reset timeouts using an external capacitor. In addition, the MAX16063 offers a manual reset input.
This device is offered in a 4mm x 4mm thin QFN package and is fully specified from -40°C to +125°C.
