MAX6466XR26+

Overview

The MAX6466XR26+T is a single-channel ultra-low-power voltage monitor manufactured by Analog Devices (Maxim Integrated). It operates within a supply voltage range of up to 6V and consumes only 3.5µA of quiescent current. The device features an active-low, open-drain reset output with a fixed threshold voltage of 2.6V and a typical reset delay time of 150ms. It provides high accuracy with a tolerance of 2.5% and is available in a compact SC-70-3 surface-mount package. The component supports an extended industrial temperature range from -40°C to +125°C, ensuring reliable performance in demanding environments.

Procurement Notes

Verify the specific suffix (+T) indicates tape-and-reel packaging when ordering. Confirm the manufacturer designation as Analog Devices Inc. or Maxim Integrated to ensure authenticity. Check RoHS compliance status for environmental regulations. Validate the operating temperature range requirements against your system specifications before procurement.

Selection Notes

Select this component when a fixed 2.6V threshold is required for single-supply monitoring. Consider the 3.5µA current draw for strict power budget constraints. Ensure the SC-70-3 package fits the PCB layout. Verify that the open-drain output interface matches the downstream logic requirements.

Part Context

This part belongs to the MAX6466 series of microprocessor supervisory circuits designed for low-voltage applications. The series offers various threshold options to accommodate different rail voltages while maintaining consistent low-power characteristics and small form factors suitable for space-constrained designs.

Replacement Considerations

Consult official datasheets for cross-reference candidates within the same family. Verify equivalent threshold voltages and package dimensions. Ensure functional compatibility regarding reset delay times and output configurations before substitution.
