MAX6333UR23D3-T

Overview

The MAX6333UR23D3-T is a microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 1.8V to 5.5V and features a fixed reset threshold voltage of 2.3V. The device provides an active-low, push-pull RESET output with a typical timeout period of 40ms. Designed for surface-mount installation, it utilizes a compact SOT-23-3 package. The component supports an extended operating temperature range from -40°C to +125°C and consumes a low quiescent current of 3.3µA.

Feature Summary

Monitors power supply voltage and asserts a reset signal when the input drops below the preset threshold
Provides an active-low push-pull output suitable for direct interfacing with microprocessor reset pins
Eliminates external components by integrating fixed threshold detection and timeout functionality

Applications

Monitoring power supplies in 1.8V to 3.3V microprocessor systems
Ensuring system reliability in digital circuits through automated power-on reset
Reducing bill-of-materials cost by removing external comparator components

Procurement Notes

Verify the exact suffix D3 against official datasheets to confirm the specific 2.3V threshold variant. Confirm RoHS compliance status and lead times with authorized distributors as availability may vary. Ensure the SOT-23-3 footprint matches your PCB design constraints before procurement.

Selection Notes

Select this component when an active-low push-pull output is required rather than open-drain. Compare against the MAX6334 series if open-drain outputs are preferred. Verify that the 2.3V threshold aligns with the target system's minimum operating voltage requirements.

Part Context

This part belongs to the MAX6332/MAX6333/MAX6334 family of ultra-low-voltage, low-power µP reset circuits. These devices are designed to increase circuit reliability and reduce cost by eliminating external components and adjustments. The MAX6333 specifically distinguishes itself with a push-pull output configuration.
