Maxim Integrated MAX6377XR26+T Voltage Supervisor

The MAX6377XR26+T from Maxim Integrated is a precision, low-power microprocessor (µP) supervisory circuit designed to monitor power supplies in µP and digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when monitoring nominal system voltages from 1.8V to 5.0V.

This compact supervisory circuit is ideal for portable and battery-powered equipment due to its low power consumption and small footprint. The MAX6377XR26+T is available in a tiny, 3-pin SC70 package, making it suitable for space-constrained applications.

Key Features:

• Voltage Monitoring: The device monitors a preset +2.63V threshold voltage (V<sub>TH) with a precision of ±1.5% over temperature, ensuring reliable system operation.
• Reset Output: It provides a reset output which remains asserted for a minimum timeout period of 140ms after V<sub>CC has risen above the reset threshold. This helps in stabilizing the system during power-up, power-down, and brownout conditions.
• Low Power Consumption: With a supply current of only 1µA, this voltage supervisor is optimized for battery-powered devices, extending the overall battery life.
• High Operating Temperature: The device can operate over a wide temperature range of -40°C to +125°C, accommodating diverse environmental conditions.
• Immune to Short V<sub>CC Transients: The MAX6377XR26+T features a built-in glitch immunity to ensure that the device does not generate false resets in response to short duration transients on the V<sub>CC line.

Applications:

• Computers and Controllers
• Portable/Battery-Powered Equipment
• Intelligent Instruments
• Embedded Systems
• Industrial Equipment

The MAX6377XR26+T voltage supervisor from Maxim Integrated offers a combination of features that make it an excellent choice for ensuring the integrity of power supplies and system operation. Its tight threshold accuracy, low power consumption, and small package size make it an ideal solution for designers looking to enhance system reliability with minimal impact on power budgets and board space.
