Processor Supervisor 2.8V 1.8V to 3.6V 4-Pin UCSP T/R

The MAX16073 ultra-small, ultralow-power, microprocessor (µP) supervisory circuits feature a precision band-gap reference, comparator, and internally trimmed resistors that set the threshold voltage. Designed to monitor the system supply voltage and assert an output during power-up, power-down, and brownout conditions, these devices provide excellent circuit reliability and low cost by eliminating external components and adjustments when monitoring nominal system voltage from 1.8V to 3.6V. The MAX16073 has a push-pull, active-high reset output. The devices are designed to ignore fast transients on VCC. The devices also include a manual reset input (??). The MAX16073 are available in a 1mm x 1mm, space-saving, 4-bump, chip-scale package (UCSP).
