MAX6353TZUK+

Overview

The MAX6353TZUK+ is a dual-input voltage supervisor IC manufactured by Analog Devices Inc. (Maxim Integrated). It monitors two independent voltage rails with threshold voltages of 2.32 V and 2.93 V. The device features an active-low, push-pull output and includes a manual reset input. It provides a fixed reset delay time of 180 ms to ensure stable power-up sequencing. The component is housed in a compact SOT-23-5 surface-mount package, designed for space-constrained applications requiring reliable dual-voltage supervision without watchdog timer functionality.

Feature Summary

• Dual-channel voltage monitoring capability for independent power rails
• Active-low push-pull output driver for direct logic interface
• Manual reset input allows external control over system reset state
• Fixed 180 ms reset delay ensures adequate power stabilization time

Applications

• Embedded communication systems requiring dual voltage supervision
• Motor control applications needing stable MCU power monitoring
• General-purpose embedded projects with multiple voltage domains

Procurement Notes

Verify current availability status as the part may be discontinued or limited supply. Confirm RoHS compliance and lead-free status through official documentation. Check for alternative packages if SOT-23-5 is unavailable. Validate threshold voltage requirements against design specifications before procurement.

Selection Notes

Select this component when dual voltage monitoring with specific thresholds of 2.32 V and 2.93 V is required. Ensure compatibility with active-low logic interfaces. Consider the 180 ms reset delay in timing-critical designs. Verify that manual reset functionality meets system requirements. Confirm package availability in SOT-23-5 format.

Part Context

The MAX6353 series belongs to Maxim Integrated's voltage supervisory family, providing reliable power management solutions. The TZUK+ suffix indicates a specific pinout and packaging variant within the MAX6353 lineup. This component addresses needs for multi-rail power monitoring in compact electronic designs.

Replacement Considerations

Check for MAX6353 variants with different threshold combinations or package types. Verify functional compatibility with existing circuit designs when substituting. Review datasheet differences for any changes in reset delay or output configuration.
