MAX16055 Ultra-small microprocessor supervisor monitors up to six power-supply voltages down to 0.5V

Multivoltage monitor with integrated reset timing in a space-saving package.

SUNNYVALE, CA—July 29, 2009—Maxim Integrated Products (NASDAQ: MXIM) introduces the MAX16055, hex-voltage microprocessor supervisor with integrated reset timing, which eliminates the need for an external capacitor. Having an ultra-small, 3mm x 3mm footprint, this device is ideal for low-voltage monitoring in multivoltage systems such as telecommunications, networking equipment, storage devices, high-end printers, and computers.

Whenever one of the six monitored voltages falls below its threshold, the open-drain reset output asserts and remains asserted for at least 140ms after all six voltages exceed their respective thresholds. The reset output is internally pulled up to V_CC to eliminate the need for an external resistor, but can be overdriven to accommodate other logic devices. A manual reset is also provided.

Maxim offers ten versions of the MAX16055, which provide different thresholds and supply tolerances to meet all low-voltage system requirements. Preset thresholds for monitoring 3.3, 3, 2.5, 1.8, 1.5, 1.2, 1.1, 1.0, and 0.9V supplies with -5% and -10% tolerance are available; additionally, adjustable versions are available to accommodate most of today's standard logic devices.

This device operates from 1V to 5.5V with the power derived from one of the monitored inputs, thereby eliminating the need for a separate V_CC pin. The MAX16055 consumes only 25microamps (typ) of quiescent current. Fully specified over the -40°C to +125°C automotive temperature range, the MAX16055 is available in a space-saving, 3mm x 3mm, 10-pin µMAX® package. Prices start at $2.33 (2500-up, FOB USA).
