MAX6356SWUT+T

Overview

The MAX6356SWUT+T is a dual/triple-voltage microprocessor supervisory circuit in a 6-pin SOT-23 package. It monitors three supply voltages: VCC1, VCC2, and an additional monitor input. The device provides active-low push-pull reset outputs referenced to VCC1 and VCC2. Key electrical parameters include a maximum supply voltage of 5.5V, a minimum operating temperature of -40°C, and a reset delay time of 280ms. It features a 20µA supply current and a 100ms minimum power-on reset pulse width.

Feature Summary

• Precision factory-set power-supply reset thresholds for multiple voltage levels
• Active-low debounced manual-reset input compatible with TTL/CMOS logic
• Outputs remain valid as long as either input supply voltage exceeds +1.0V

Applications

• Multi-rail embedded system power monitoring
• Microprocessor reset generation in industrial control units
• Battery-powered device voltage supervision

Procurement Notes

Verify the suffix 'SWUT' corresponds to the specific voltage thresholds required for your design, as the MAX6356 series offers various threshold options. Confirm the '+T' indicates tape-and-reel packaging if automated assembly is planned. Ensure the component is sourced from authorized distributors to guarantee authenticity and traceability, as counterfeits may exist for popular supervisor ICs.

Selection Notes

Select this part when simultaneous monitoring of two main supplies plus a third auxiliary voltage is necessary. The SOT-23-6 package suits space-constrained designs. Consider the 280ms reset delay and 100ms POR pulse width against system startup requirements. Verify that the monitored voltage levels align with the available factory-set thresholds for the SWUT variant.

Part Context

The MAX6356 belongs to Maxim Integrated's family of multi-voltage supervisors designed to enhance system reliability. Unlike discrete solutions, these ICs integrate multiple monitoring functions into a single small footprint. The series supports various voltage thresholds and includes features like watchdog timers in other variants, but the MAX6356 specifically focuses on triple-voltage monitoring without a watchdog function.

Replacement Considerations

The MAX6356TWUT+T is a documented substitute within the same series, differing primarily in voltage threshold configuration. Verify that the threshold levels of the replacement match the original design requirements before substitution.
