MAX6353SZUK+T

Overview

The MAX6353SZUK+T is a dual-channel voltage supervisor IC manufactured by Analog Devices Inc. (Maxim Integrated). It monitors two independent voltage rails, with specified threshold voltages of 2.32 V and 2.93 V. The device features an active-low, push-pull output configuration and includes a manual reset input for system control. 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 efficient space utilization in portable and embedded electronics applications requiring reliable power management.

Feature Summary

• Dual-channel monitoring capability for independent voltage rails
• Active-low push-pull output interface for direct logic connection
• Integrated manual reset input for user-controlled system recovery
• Fixed 180 ms reset delay to prevent premature reset during power transitions

Applications

• Portable electronic devices requiring dual voltage supervision
• Embedded systems with multiple power domains
• Battery-operated equipment needing low-voltage detection
• Industrial control modules requiring stable power sequencing

Procurement Notes

Verify the exact suffix (+T) indicates tape-and-reel packaging when sourcing. Confirm the manufacturer is Analog Devices Inc. or Maxim Integrated, as legacy branding may vary. Check RoHS compliance status explicitly in the current datasheet. Ensure the SOT-23-5 footprint matches your PCB design constraints. Validate that the 2.32 V and 2.93 V thresholds align with your specific circuit requirements before procurement.

Selection Notes

Select this component when dual voltage monitoring is required in a minimal footprint. The SOT-23-5 package suits space-constrained designs. Verify that the active-low push-pull output drives your downstream logic correctly. Ensure the 180 ms delay meets your system's power-up timing specifications. Confirm compatibility with the target voltage rails (1.8V, 2.5V, 3V, 3.3V, 5V) supported by the monitored thresholds.

Part Context

The MAX6353 series belongs to Maxim Integrated's line of multi-voltage supervisors. These components are designed for applications requiring simultaneous monitoring of multiple power supplies. The SZUK variant specifically denotes the SOT-23-5 package with tape-and-reel delivery. This family supports various threshold combinations to accommodate different system architectures.

Replacement Considerations

Check for MAX6353 variants with different threshold combinations if voltage levels differ. Verify package compatibility with SOT-23-5 footprints. Consider alternatives from Analog Devices' supervisor portfolio if lead times are critical. Ensure functional equivalence in reset delay and output type.
