MAX6333UR23D

Overview

The MAX6333UR23D is a microprocessor supervisory circuit designed for 1.8V to 3.3V systems. It monitors the VCC supply voltage and asserts an active-low, push-pull RESET output when the voltage declines below a preset threshold of 2.3V. The device maintains the reset signal asserted for a minimum timeout period of 100ms after VCC rises above the threshold. It operates within a supply voltage range up to 5.5V and functions across a temperature range of -40°C to +125°C.

Feature Summary

• Monitors power supply voltage to ensure system reliability by asserting reset signals during undervoltage conditions.

Applications

• Microprocessor (µP) supervisory circuits
• Digital system power monitoring

Procurement Notes

Verify the exact suffix against official documentation, as 'MAX6333UR23D' may represent a truncated identifier compared to standard tape-and-reel part numbers like MAX6333UR23D3+T. Confirm RoHS compliance status and specific package availability through authorized distributors or manufacturer channels before procurement.

Selection Notes

Select this component for applications requiring a simple, low-power voltage supervisor with a push-pull output. Ensure the 2.3V threshold aligns with the target system's logic levels. Verify that the 100ms reset delay meets the timing requirements of the monitored microprocessor or digital circuit.

Part Context

This part belongs to the MAX6332/MAX6333/MAX6334 family of ultra-low-voltage, low-power µP reset circuits. These devices eliminate external components and adjustments by integrating fixed thresholds and timeout periods into a compact SOT-23-3 package.
