MAX6803US46D1-T

Supervisors Overview

The MAX6803US46D1-T is a power management supervisor IC manufactured by Analog Devices Inc./Maxim Integrated. It monitors a single voltage channel and provides system reset functionality. The device features a push-pull, totem pole output with an active high reset signal. Key electrical parameters include a voltage threshold of 4.63V and a minimum reset timeout of 1ms. It operates within a temperature range of -40°C to 125°C (TA). The component is housed in a SOT-143-4 package, also identified as TO-253-4 or TO-253AA, and supports surface mount mounting types.

Supervisors Feature Summary

• Monitors a single voltage channel for system supervision
• Provides active high reset signal via push-pull output
• Operates across extended industrial temperature ranges

Supervisors Applications

• Power management supervision in electronic systems

Supervisors Procurement Notes

Verify the exact suffix designation (+T vs -T) as availability may vary. Confirm the manufacturer status, as some listings indicate this product is no longer manufactured. Ensure compatibility with existing PCB layouts using the SOT-143-4 package. Check for lead-free compliance if required by specific project standards. Validate the operating temperature range against environmental conditions.

Supervisors Selection Notes

Select this component when a single-channel voltage supervisor with a 4.63V threshold is required. Consider the active high reset polarity and push-pull output drive capability. Evaluate the 1ms minimum reset timeout against system startup requirements. Ensure the SOT-143-4 package fits the available board space. Verify that the extended temperature range meets the application's thermal constraints.

Supervisors Part Context
