MAX6315US48D3

Supervisors Overview

The MAX6315US48D3 is a voltage supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It monitors a single input with a threshold voltage of 4.8 V and an overvoltage threshold of 4.87 V. The device features an active low, open-drain output and supports manual reset functionality without a watchdog timer or battery backup switch. It operates within a supply voltage range up to 5.5 V and includes a reset delay time of 200 ms. The component consumes 5 uA of operating current and dissipates 320 mW of power. It is housed in a SOT-143-4 package and functions reliably between -40 C and +125 C.

Supervisors Feature Summary

• Provides system reset assertion when monitored supply falls below programmed threshold
• Features active low open-drain output for flexible interface compatibility
• Supports manual reset input for user-initiated system recovery

Supervisors Applications

• Portable electronic devices requiring low standby current
• Microprocessor systems needing reliable power supervision
• Battery-operated equipment monitoring voltage levels

Supervisors Procurement Notes

Verify availability status as this part may be subject to limited supply or obsolescence. Confirm RoHS compliance details through official documentation before procurement. Ensure the specific suffix matches required packaging options such as reel or cut tape. Cross-reference manufacturer datasheets for accurate ordering information and lead times.

Supervisors Selection Notes

Select this component for applications requiring precise voltage monitoring with minimal quiescent current. The SOT-143-4 package suits space-constrained designs. Verify that the 4.8 V threshold aligns with the target supply rail. Consider the open-drain output requirement for pull-up resistor implementation in the final circuit design.

Supervisors Part Context

This device belongs to the MAX6315 series of microprocessor supervisory circuits designed for low-power applications. The series offers various threshold voltages to accommodate different supply rails. Manufactured by Maxim Integrated, now part of Analog Devices, these components are widely used in consumer electronics and industrial control systems for power management.

Supervisors Replacement Considerations

Check for direct substitutes within the MAX6315 family with compatible thresholds. Verify pinout compatibility with existing PCB layouts. Ensure replacement parts maintain similar electrical characteristics including reset delay and operating temperature range.
