MAX6332UR16D3+

Overview

The MAX6332UR16D3+ is a microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors power supply voltages in 1.8V to 3.3V systems, asserting an active-high reset signal when the supply voltage drops below a preset threshold of 1.6V. The device operates within a supply voltage range up to 5.5V and features a push-pull output configuration. It is housed in a compact SOT-23-3 package, designed for surface-mount installation with an operating temperature range from -40°C to +125°C.

Feature Summary

• Monitors power supply voltage and asserts a reset signal when the input falls below a fixed threshold
• Provides an active-high reset output with push-pull drive capability
• Eliminates external components by integrating fixed threshold detection and timeout functions

Applications

• Microprocessor (µP) system power supply monitoring
• Digital system voltage supervision
• Battery-powered equipment power management

Procurement Notes

Verify the manufacturer designation as Analog Devices Inc./Maxim Integrated on official datasheets. Confirm the specific suffix D3 indicates the 1.6V threshold variant. Ensure the package matches the SOT-23-3 specification. Check RoHS compliance status against current regulatory requirements before procurement.

Selection Notes

Select this component when an active-high reset output is required for the target logic interface. The fixed 1.6V threshold suits applications monitoring 1.8V or 3.3V rails where undervoltage protection is critical. Consider the SOT-23-3 footprint constraints and the specified operating temperature range for environmental compatibility.

Part Context

This part belongs to the MAX6332/MAX6333/MAX6334 family of ultra-low-voltage, low-power µP reset circuits. While the MAX6333 offers an active-low push-pull output and the MAX6334 provides an active-low open-drain output, the MAX6332 is distinguished by its active-high reset signal, catering to specific logic compatibility needs.
