Description

The MAX6468US26D3-T is an electronic component, specifically categorized as an IC chip. It is a microprocessor (µP) supervisory circuit that monitors single power-supply voltages, ranging from +1.8V to +5.0V. This circuit asserts a reset if the supply voltage drops below its preset threshold. Additionally, it includes an edge-triggered, one-shot manual reset function to ensure the µP enters the reset mode for a fixed timeout period.

Compared to traditional manual reset supervisory circuits, the MAX6468US26D3-T significantly improves system reliability. It is designed to be immune to short voltage transients and operates over a wide temperature range of -40°C to +125°C.
