MAX6333UR16D3-T

Overview

The MAX6333UR16D3-T is a single-channel voltage supervisory circuit from the MAX6333 series, manufactured by Analog Devices Inc. (Maxim Integrated). It monitors a single power supply input with a fixed reset threshold of 1.6V. The device features an active-low, push-pull RESET output and operates within a supply voltage range up to 5.5V. It includes a typical reset delay time of 200ms and consumes only 3.3µA of quiescent current. The component is housed in a compact SOT-23-3 surface-mount package and supports an extended industrial temperature range from -40°C to +125°C.

Feature Summary

• Provides reliable system reset via active-low push-pull output when supply voltage drops below the preset threshold
• Ultra-low power consumption ensures minimal impact on battery-operated applications
• Compact three-pin SOT-23 package facilitates space-constrained PCB layouts

Applications

• Microprocessor (µP) power supply monitoring in digital systems
• Battery-powered portable electronic devices requiring low standby current
• Consumer electronics and industrial control boards needing simple voltage supervision

Procurement Notes

Verify the exact suffix designation, as 'T' typically indicates tape-and-reel packaging while other variants may differ. Confirm RoHS compliance status through official datasheets or manufacturer declarations. Check for obsolescence notices or lifecycle changes directly from Analog Devices, as distribution availability varies by region and channel. Ensure the specific threshold voltage matches design requirements before procurement.

Selection Notes

Select this component when a fixed 1.6V threshold is required for active-low reset signaling. Compare against MAX6333 variants with different thresholds if system voltage levels differ. Consider the push-pull output capability for driving loads directly without external pull-up resistors. Evaluate thermal performance within the specified operating temperature range for the intended application environment.

Part Context

This part belongs to the MAX6332/MAX6333/MAX6334 family of 3-pin, ultra-low-voltage, low-power µP reset circuits. These devices eliminate external components by integrating fixed thresholds and timeout periods. The MAX6333 specifically offers an active-low push-pull output, distinguishing it from the open-drain MAX6334 and active-high MAX6332.

Replacement Considerations

MAX6333UR16D3+T is a verified equivalent part number offering identical electrical specifications and pinout compatibility.
