MAX6335US16D3

Overview

The MAX6335US16D3 is a microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within an extended temperature range of -40°C to +125°C and utilizes a SOT-143-4 surface-mount package. The device monitors a single voltage channel with a fixed threshold of 1.6V. It features a push-pull, totem pole output that asserts a reset signal active high when the supply voltage drops below the preset threshold or upon manual reset input activation. The minimum reset timeout duration is specified at 100ms.

Feature Summary

• Monitors power supply voltage for reliable system operation
• Includes debounced manual-reset input functionality
• Asserts reset signal during under-voltage conditions
• Eliminates need for external components and adjustments

Applications

• 1.8V to 3.3V microprocessor systems
• Digital system power supervision
• Battery-powered equipment monitoring

Procurement Notes

Verify the manufacturer designation as Analog Devices Inc./Maxim Integrated on official documentation. Confirm the specific suffix D3 corresponds to the SOT-143-4 package and 1.6V threshold variant. Ensure compatibility with the required operating temperature range of -40°C to +125°C for your application environment before procurement.

Selection Notes

Select this component when a simple reset function with a 1.6V threshold is required for low-voltage digital systems. The active-high push-pull output suits direct interfacing with logic inputs. Consider the SOT-143-4 package size for space-constrained designs requiring surface-mount assembly.

Part Context

This part belongs to the MAX6335/MAX6336/MAX6337 series of ultra-low-voltage, low-power microprocessor reset circuits. These devices are designed to increase circuit reliability in µP and digital systems by providing precise supervision without external adjustments. The series supports various threshold voltages and packages to accommodate different system requirements.

Replacement Considerations

Check for MAX6335 variants with different thresholds or packages if the 1.6V level is unsuitable. Verify pinout compatibility with existing PCB layouts when substituting.
