MAX6352MSUK

Overview

The MAX6352MSUK+ is a dual microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors two independent power supply inputs to ensure system reliability. The device features active-low, open-drain reset outputs and supports manual reset functionality. It operates within an extended temperature range of -40°C to +85°C and is housed in a compact SOT-23-5 surface-mount package. The circuit draws low quiescent current, making it suitable for battery-powered applications.

Feature Summary

• Dual voltage monitoring capability for multiple power rails
• Active-low debounced manual reset input
• Low power consumption with minimal supply current
• Compact surface-mount packaging for space-constrained designs

Applications

• Portable electronic devices requiring multi-voltage supervision
• Battery-operated systems needing power-fail detection
• Embedded controllers requiring reliable reset generation
• Industrial equipment monitoring critical supply voltages

Procurement Notes

Verify the specific suffix variant (e.g., MSUK) against the manufacturer's current datasheet to confirm threshold voltages and pinout compatibility. Confirm RoHS compliance status and lead-free certification requirements before integration. Check for end-of-life notices or obsolescence warnings as this component series may have limited availability from original manufacturers.

Selection Notes

Select this component when dual-supervision is required without watchdog timer functionality. Compare threshold voltage options against target supply rails to ensure accurate reset assertion. Evaluate package size constraints against the SOT-23-5 footprint. Consider alternative single-channel supervisors if only one rail requires monitoring to reduce cost and board space.

Part Context

This part belongs to the MAX63xx family of microprocessor supervisory circuits designed for precision voltage monitoring. These devices improve system reliability by replacing discrete components with integrated solutions. The family offers various threshold levels and package options to accommodate diverse industrial and consumer electronics applications.
