MAX6315US40D1+T

Supervisors Overview

The MAX6315US40D1+T is a power supply support circuit manufactured by Analog Devices Inc./Maxim Integrated. It functions as a fixed, single-channel supervisory IC housed in a lead-free SOT-143-4 package. The device monitors one input voltage with a threshold of 4.0 V and features an active low, open-drain output. Key electrical parameters include a reset delay time of 1.4 ms, a maximum operating temperature of +125 °C, and a minimum operating temperature of -40 °C. It operates within a maximum supply voltage of 5.5 V and consumes a working supply current of 5 µA. The accuracy is specified at 1.8%, and it supports manual reset functionality without a watchdog timer or battery backup switch.

Supervisors Feature Summary

• Provides simple reset and power-on reset supervision for single-channel applications
• Features an open-drain output compatible with various logic families
• Includes manual reset capability for system control flexibility

Supervisors Applications

• Portable equipment requiring low-power voltage monitoring
• Battery-powered systems needing efficient power management
• Microprocessor reset circuits in embedded designs

Supervisors Procurement Notes

Verify the manufacturer designation matches Analog Devices Inc. or Maxim Integrated to ensure authenticity. Confirm the suffix '+T' indicates tape-and-reel packaging if required for automated assembly. Check RoHS compliance documentation for environmental standards. Ensure the SOT-143-4 package type aligns with your PCB footprint requirements. Validate the specific threshold voltage variant corresponds to the design needs.

Supervisors Selection Notes

Select this component when a fixed threshold supervisor is needed for a single voltage rail. The low quiescent current makes it suitable for battery-operated devices. Consider the open-drain output configuration for level shifting or wired-OR connections. Verify that the 1.4 ms reset delay meets the timing requirements of the monitored system. Ensure the operating temperature range covers the intended application environment.

Supervisors Part Context

This part belongs to the MAX6315 series of microprocessor supervisors. The series offers various fixed threshold voltages and package options. Analog Devices acquired Maxim Integrated, hence the dual branding. These ICs are designed for reliable power management in compact electronic systems.

Supervisors Replacement Considerations

Check for other MAX6315 variants with different threshold voltages if the 4.0 V setting is not suitable. Verify pinout compatibility with alternative supervisor ICs from other manufacturers before substitution.
