MAX6326UR29-T

MAX6326UR29-T Description

The MAX6326UR29-T is a precision voltage supervisor IC from Analog Devices Inc./Maxim Integrated, designed to monitor single-voltage power supplies in electronic systems. This SOT23-3 packaged device ensures reliable operation by generating a reset signal when the supply voltage drops below the fixed threshold of 2.93V, safeguarding microcontrollers, FPGAs, and other critical components from unstable power conditions. With a 100ms minimum reset timeout, it guarantees sufficient time for system stabilization upon power-up or brownout recovery. Although marked as obsolete, it remains a robust choice for legacy designs requiring dependable power monitoring.

MAX6326UR29-T Features

• Fixed Threshold Voltage: Precisely monitors 2.93V with tight tolerance, eliminating the need for external components.
• Active-Low Reset Output: Provides a low signal during undervoltage events, compatible with most µP/µC reset inputs.
• Compact SOT23-3 Package: Ideal for space-constrained applications.
• 100ms Minimum Reset Timeout: Ensures stable system startup or recovery.
• RoHS3 Compliant & REACH Unaffected: Meets environmental regulations.
• Wide Operating Range: Suitable for industrial and consumer electronics.
• Moisture Sensitivity Level (MSL) 1: Unlimited shelf life and ease of handling.

MAX6326UR29-T Applications

• Embedded Systems: Resets microcontrollers during power anomalies.
• Industrial Controls: Protects PLCs and sensors from voltage fluctuations.
• Automotive Electronics: Ensures reliable operation in infotainment or ADAS modules.
• Battery-Powered Devices: Monitors Li-ion or NiMH battery levels to prevent data corruption.
• Legacy Equipment Maintenance: Replaces older supervisors in repairs or upgrades.
