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

The MAX16074 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 MAX16074 has an open-drain active-low reset output. The devices are designed to ignore fast transients on VCC. The devices also include a manual reset input (??). The MAX16074 are available in a 1mm x 1mm, space-saving, 4-bump, chip-scale package (UCSP).
