Maxim Integrated Products introduces the MAX16072–MAX16074 microprocessor (µP) supervisory circuits in a 1mm x 1mm chip-scale package. These low-power devices provide excellent circuit reliability and low cost by eliminating the need for multiple external resistors and adjustments normally required when monitoring nominal system voltages from 1.8V to 3.6V. Their compact footprint and supply current of 0.7µA make them ideal for space-constrained portable applications such as cellular phones, MP3 players, and GPS equipment.

The MAX16072–MAX16074 offer multiple factory-fixed reset thresholds and timeout options, and are designed to ignore fast transients on VCC. They include an active-low manual-reset input, precision band-gap reference, comparator, and internally trimmed resistors. The MAX16072 is available with a push-pull, active-low reset output; the MAX16073 with a push-pull, active-high reset output; and the MAX16074 with an open-drain, active-low reset output.

The MAX16072–MAX16074 are available in a space-saving (1mm x 1mm) 4-bump UCSP™ package. These devices are fully specified and guaranteed over the -40°C to +85°C extended industrial temperature range. Prices start at $0.90. (1000-up, FOB USA). Samples are now available.
