MAX6351LSUT+

Overview

The MAX6351LSUT+T is a dual-channel microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It operates within an extended temperature range of -40°C to +85°C and utilizes a surface-mount SOT-23-6 package. The device provides active-low, push-pull reset outputs with a minimum power-on reset pulse width of 100ms. It features precision factory-set thresholds for two monitored voltages: 2.93V and 4.63V. The circuit includes a debounced manual reset input and consumes only 20µA of supply current.

Feature Summary

• Dual voltage monitoring with fixed precision thresholds
• Active-low push-pull reset outputs referenced to VCC1
• Debounced manual reset input compatible with TTL/CMOS logic

Applications

• Multi-supply system reliability monitoring
• Embedded controller power supervision
• Industrial equipment voltage tracking

Procurement Notes

Verify the specific suffix 'L' against official datasheets to confirm threshold accuracy and output configuration. Ensure the ordering part number matches the required package variant and tape-and-reel specifications. Confirm RoHS compliance status through manufacturer documentation prior to procurement.

Selection Notes

Select this component when simultaneous monitoring of two distinct voltage rails is required. The push-pull output architecture supports direct interfacing with digital logic without external pull-up resistors. Verify that the fixed threshold levels align with the target supply voltages in the design.

Part Context

This device belongs to the MAX6351-MAX6360 family of µP supervisors designed to improve system accuracy compared to discrete components. These circuits assert reset signals when input supplies drop below preset thresholds, ensuring valid operation as long as inputs remain above +1.0V.

Replacement Considerations

Cross-reference with MAX6351 variants sharing the same L-series thresholds and SOT-23-6 packaging. Verify functional equivalence regarding output drive type and reset timing characteristics before substitution.

FAQ
