MAX6356TZUT+T

Overview

The MAX6356TZUT+T is a triple voltage supervisor IC from the MAX6351–MAX6360 series, manufactured by Analog Devices Inc./Maxim Integrated. It monitors three input supply voltages with preset thresholds of 2.93V, 4.63V, and an adjustable level. The device features an active-low push-pull reset output referenced to VCC1 and includes a debounced manual reset input. It operates within a supply voltage range up to 5.5V and supports a minimum power-on reset pulse width of 100ms. The component is housed in a surface-mount SOT-23-6 package and functions reliably across an extended temperature range of -40°C to +85°C.

Feature Summary

• Monitors three distinct voltage inputs simultaneously to ensure system power integrity
• Provides an active-low push-pull reset output for direct interface with microprocessors
• Includes a debounced manual reset input compatible with TTL/CMOS logic levels

Applications

• Microprocessor system supervision for multi-rail power architectures
• Battery-powered devices requiring precise voltage threshold monitoring
• Industrial control systems operating in extended temperature environments

Procurement Notes

Verify the specific suffix 'TZ' against the manufacturer's official part numbering guide to confirm the exact voltage threshold configuration. Ensure the ordering code matches the required SOT-23-6 packaging format. Cross-reference the datasheet revision date to confirm compatibility with current design specifications. Confirm RoHS compliance status if required by regulatory standards.

Selection Notes

Select this component when simultaneous monitoring of three voltage rails is required within a compact footprint. The push-pull output eliminates the need for external pull-up resistors, simplifying board layout. Consider the adjustable threshold option for custom voltage requirements. Verify that the 100ms minimum reset pulse width aligns with the target microprocessor's startup timing constraints.

Part Context

This part belongs to the MAX635x family of microprocessor supervisors designed to improve system reliability compared to discrete components. The series offers precision factory-set thresholds for common supply voltages like 1.8V, 2.5V, 3.0V, 3.3V, and 5V. These devices are engineered to assert reset outputs if any monitored supply drops below its threshold, ensuring stable operation during power transitions.

FAQ

What is the reference voltage for the reset output?

The reset output is active-low and referenced to VCC1.

Does the MAX6356 include a watchdog timer?

No, the MAX6356 does not offer a watchdog timer; this feature is available in other variants like the MAX6358 or MAX6359.
