MAX6357TWUT+

Overview

The MAX6357TWUT+T is a triple voltage microprocessor supervisor in an SOT-23-6 package. It monitors three input supplies with thresholds of 1.67V, 3.08V, and an adjustable level. The device features active-low push-pull outputs referenced to VCC2, a debounced manual reset input, and a minimum power-on reset pulse width of 100ms. Operating from -40°C to +85°C, it draws 20µA supply current and supports a maximum supply voltage of 5.5V.

Feature Summary

• Monitors three independent voltage inputs simultaneously
• Provides active-low push-pull reset outputs referenced to the secondary supply rail
• Includes a debounced manual reset input for system control
• Ensures reliable startup with a minimum 100ms power-on reset pulse

Applications

• Multi-rail embedded systems requiring simultaneous voltage supervision
• Microprocessor power management circuits
• Portable electronics with multiple voltage domains

Procurement Notes

Verify component authenticity through authorized channels as this part is discontinued. Confirm exact threshold specifications against the official datasheet since suffixes define specific voltage levels. Check RoHS compliance status and ensure the SOT-23-6 footprint matches your PCB design requirements before integration.

Selection Notes

Select this component when triple voltage monitoring is required in a compact surface-mount package. Ensure the adjustable threshold meets your specific third-rail requirement. Verify that the push-pull output configuration aligns with your downstream logic interface needs and that the 100ms reset delay suits your system startup timing constraints.

Part Context

This device belongs to the MAX635x series of low-power supervisors designed for improving system reliability. It replaces discrete monitoring components by integrating multiple thresholds into a single chip. The series offers various pinout options and threshold combinations to accommodate diverse multi-supply architectures in industrial and consumer applications.

Replacement Considerations

Public confirmed substitute part numbers are not available due to the discontinued status of this specific variant.
