MAX6332UR23D3

Overview

The MAX6332UR23D3 is a voltage supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 1.8 V to 5.5 V and features a fixed threshold voltage of 2.3 V for monitoring a single input. The device provides an active low, open-drain reset output with a typical reset delay time of 40 ms. It consumes a maximum operating supply current of 3.3 µA and dissipates up to 320 mW. The component functions reliably across an extended temperature range from -40°C to +125°C.

Feature Summary

• Provides system supervision by monitoring input voltage levels
• Generates a reset signal when voltage drops below the specified threshold
• Operates with ultra-low power consumption suitable for battery applications

Applications

• Digital system processor reset generation
• Battery-powered equipment power management
• Portable electronic device voltage supervision

Procurement Notes

Verify the specific suffix D3 against official datasheets to confirm pinout and electrical characteristics match design requirements. Confirm RoHS compliance status through manufacturer documentation before integration. Check availability status as distribution channels may vary. Ensure the open-drain output configuration aligns with the host processor interface logic requirements.

Selection Notes

Select this component when a simple, low-power supervisor is required for single-voltage monitoring. The open-drain output necessitates an external pull-up resistor, which must be accounted for in the circuit design. Compare the 2.3 V threshold against the target system's minimum operating voltage to ensure proper reset timing. Consider the SOT-23-3 package size for space-constrained layouts.

Part Context

This part belongs to the MAX6332/MAX6333 family of microprocessor reset circuits. These devices are designed to monitor power supplies in digital systems without requiring external components for basic operation. The family offers various threshold voltages and output configurations to suit different system architectures.

Replacement Considerations

Check the official MAX6332 datasheet for listed equivalent parts or alternative suffixes that may offer compatible performance. Verify pin compatibility and electrical specifications before substituting.
