MAX16072/MAX16073/ nanoPower P Supervisory Circuits in a MAX16074 4-Bump (1mm x 1mm) Chip-Scale Package General Description Features The MAX16072/MAX16073/MAX16074 ultra-small, ultra- Ultra-Low, 0.7A Supply Current low-power, microprocessor (P) supervisory circuits feature Ultra-Small (1mm x 1mm), 4-Bump UCSP a precision band-gap reference, comparator, and 20s, 8ms, 34ms, and 140ms Reset Timeout internally trimmed resistors that set the threshold voltage. Options Available Designed to monitor the system supply voltage and assert Factory-Trimmed Reset Thresholds Available from an output during power-up, power-down, and brownout conditions, these devices provide excellent circuit reliability 1.58V to 3.08V in Approximately 100mV Increments and low cost by eliminating external components and 2.5% Threshold Accuracy Over Temperature adjustments when monitoring nominal system voltage Manual Reset Input from 1.8V to 3.6V. Guaranteed Reset Valid to V = 1.0V CC The MAX16072 has a push-pull, active-low reset output, Immune to Short V Transient the MAX16073 has a push-pull, active-high reset output, CC and the MAX16074 has an open-drain active-low reset output. The devices are designed to ignore fast transients on V . The devices also include a manual reset input CC Ordering Information (MR). PIN- The MAX16072/MAX16073/MAX16074 are available in a PART RESET OUTPUT TYPE PACKAGE 1mm x 1mm, space-saving, 4-bump, chip-scale package (UCSP).
