Microprocessor supervisory chip by Maxim

Maxim has introduced the MAX16072-MAX16074 microprocessor (µP) supervisory chip in a 1mm x 1mm chip-scale package. These devices are low-power devices and is said to eliminate 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 low supply current (0.7µA) makes them useful for space-constrained portable applications such as cellular phones, MP3 players, and GPS equipment.

These circuits offer multiple factory-fixed reset thresholds and timeout options and are designed to ignore fast transients on VCC. They consist of 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.

Package: (1mm x 1mm) 4-bump UCSP
