MAX6333UR24D2-T

Overview

The MAX6333UR24D2-T is a microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It monitors power supplies in 1.8V to 3.3V systems, asserting an active-low reset signal when the supply voltage drops below a preset threshold of 2.4V. The device features a push-pull output and a typical reset delay time of 40 ms. It operates within a supply voltage range up to 5.5V and consumes a working current of 3.3 uA. The component is housed in a SOT-23-3 package and supports surface mount installation across a temperature range of -40°C to +125°C.

Feature Summary

• Monitors power supply voltages to ensure system reliability
• Provides active-low reset signal with push-pull output configuration
• Eliminates need for external components and adjustments

Applications

• Microprocessor (µP) supervisory circuits
• Digital system power monitoring
• Voltage supervision in low-voltage applications

Procurement Notes

Verify the exact suffix against official documentation, as 'T' typically indicates tape-and-reel packaging while other suffixes may denote cut tape or bulk. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer, as availability varies by region and production lifecycle stage. Ensure the specific part number matches your design requirements before ordering.

Selection Notes

Select this component when a simple, low-power voltage supervisor with a push-pull output is required. Compare with MAX6332 for active-high output needs or MAX6334 for open-drain configurations. Verify that the 2.4V threshold aligns with your system's minimum operating voltage and that the 40ms timeout meets your reset timing constraints.

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 integrating essential power management functions into a small 3-pin package. The family shares similar electrical characteristics but differs primarily in output polarity and type.

Replacement Considerations

MAX6333UR24D2+T is the lead-free version of this component. MAX6333UR23D2+T offers a 2.3V threshold. MAX6332 series provides active-high outputs, while MAX6334 series provides open-drain outputs. Verify pinout compatibility and electrical specifications before substitution.
