MAX6339 - Quad Voltage P Supervisory Circuit

Description

The MAX6339 is a precision quad voltage monitor with microprocessor (µP) supervisory reset timing.

The device can monitor up to four system supply voltages without any external components and asserts a single reset if any supply voltage drops below its preset threshold.

Features

  • o Monitors Four Power-Supply Voltages o Precision Factory-Set Reset Threshold Options for +5.0V, +3.3V, +3.0, +2.5V, +1.8V, and -5.0V Supplies o User-Adjustable Voltage Monitoring Threshold Options o Low 55µA Supply Current o Open-Drain RESET Output with 10µA Internal Pullup o 140ms (min) Reset Timeout Period o RESET Valid to IN1 = 1V or IN2 = 1V o Immune to Short Monitored Supply Transients o No External Components Required o Guaranteed from -40°C to +85°C o Small 6-Pin SOT23 Package MAX6339.

19-1756; Rev 2; 10/01 Quad Voltage µP Supervisory Circuit in SOT Package General Description The MAX6339 is a precision quad voltage monitor with microprocessor (µP) supervisory reset timing. The device can monitor up to four system supply voltages without any external components and asserts a single reset if any supply voltage drops below its preset threshold. The device significantly reduces system size and component count while improving reliability compared to separate ICs or discrete components. A variety of factory-trimmed threshold voltages are available to accommodate different supply voltages and tolerances with minimal external component requirements. The selection includes internally fixed options for monitoring +5.0V, +3.3V, +3.0V, +2.5V, +1.8V, and -5.
