MAX6338JUB+

The MAX6338JUB+ from Analog Devices (formerly Maxim Integrated) is a versatile quad voltage monitor IC. It is capable of monitoring up to four different supply voltages simultaneously, offering flexibility with factory-trimmed or user-adjustable threshold voltages. The device supports nominal input voltages including +5.0V, +3.3V, +3.0V, +2.5V, +1.8V, and -5.0V, with trip thresholds available for 5% or 10% power-supply tolerances.

Key electrical characteristics include a low supply current of 25µA typical and an operating supply voltage range of +2.5V to +5.5V. The MAX6338JUB+ features four independent, open-drain, active-low outputs, each with an independent output for each monitored voltage. An internal undervoltage lockout circuit ensures all digital outputs go low when VCC drops below the minimum operating voltage. The outputs have weak internal pull-ups to VCC, enabling wire-ORed connections.

Designed for reliability, the MAX6338JUB+ guarantees performance across an extended operating temperature range of -40°C to +85°C. It requires no external components for its core functionality. The component is housed in a compact 10-pin µMAX package, suitable for space-constrained applications. Its robust design makes it suitable for telecommunications, high-end printers, desktop and notebook computers, data storage equipment, networking equipment, industrial equipment, and set-top boxes.
