MAX6333UR16D3+T

Overview

The MAX6333UR16D3+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 an active-low, push-pull reset output. The device monitors a single input with a threshold voltage of 1.6V. It provides a reset delay time of 200ms and consumes a typical operating current of 3.3µA. The component is housed in a SOT-23-3 package and supports surface-mount installation. It functions without manual reset or watchdog timer capabilities.

Feature Summary

• Monitors power supply voltage to assert reset signal when declining below preset threshold
• Provides active-low push-pull output for direct interface with digital systems
• Ultra-low power consumption suitable for battery-operated applications

Applications

• Microprocessor (µP) system supervision
• Digital system power monitoring
• Low-voltage electronic circuits requiring reliable reset generation

Procurement Notes

Verify component authenticity through authorized distributors due to potential counterfeit risks. Confirm RoHS compliance status and manufacturing date codes prior to integration. Check availability constraints as this specific variant may have limited stock or obsolescence notices from the manufacturer. Ensure proper handling procedures for surface-mount components during assembly.

Selection Notes

Select this component when a low-cost, single-channel supervisor with push-pull output is required. Compare against MAX6333 variants with different thresholds or open-drain outputs if system compatibility differs. Consider thermal performance and package size constraints relative to PCB layout requirements. Validate electrical parameters against target application voltage ranges.

Part Context

Part of the MAX6332/MAX6333/MAX6334 family designed for 1.8V to 3.3V µP and digital systems. These devices eliminate external components and adjustments by performing a single reset function. The MAX6333 specifically offers an active-low push-pull output, distinguishing it from the MAX6332's active-high push-pull and MAX6334's active-low open-drain configurations.

Replacement Considerations

MAX6333UR16D2+T: Similar device with potentially different reset timeout characteristics. Verify threshold voltage accuracy and output drive capability before substitution. Cross-reference datasheet specifications for temperature range and current consumption differences.
