VOLTAGE SUPERVISOR 5.5V TQFN-24
The MAX16063 is a 1% accurate, adjustable, quad win- dow 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 pro- viding a fault signal when any of the voltages exceed their overvoltage thresholds or fall below their undervolt- age thresholds. The MAX16063 offers user-adjustable voltage thresh- olds 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 out- put. 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 time- out is internally set to 140ms (min), but can be external- ly 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 pack- age and is fully specified from -40°C to +125°C.
