TL7700CPWR

Supervisors Overview

The TL7700CPWR is a voltage supervisory circuit manufactured by Texas Instruments in an 8-pin TSSOP package. It monitors a single input voltage with an adjustable threshold, featuring an active-low open-drain output. The device operates within a supply voltage range of 1.8 V to 40 V and supports a programmable reset delay time. It maintains a typical quiescent current of 600 µA and offers a threshold accuracy of 2%. The component functions reliably across an extended temperature range from -40 °C to +85 °C.

Supervisors Feature Summary

• Adjustable under-voltage threshold for flexible system monitoring
• Programmable reset delay time to accommodate specific timing requirements
• Low power consumption with 600 µA quiescent current
• Active-low open-drain output configuration

Supervisors Applications

• Microprocessor power supply supervision
• Battery-powered system voltage monitoring
• Portable equipment power management
• Embedded controller reset generation

Supervisors Procurement Notes

Verify the complete part number including suffixes to ensure correct packaging and temperature grade. Confirm that the TSSOP-8 footprint matches your PCB design constraints. Check RoHS compliance status if required by your manufacturing standards. Ensure the supplier provides valid traceability documentation for quality assurance purposes.

Supervisors Selection Notes

Select this component when an adjustable voltage threshold is required for system supervision. Consider the 600 µA quiescent current impact on overall battery life. Verify that the open-drain output interface is compatible with the downstream logic levels. Ensure the operating temperature range meets the environmental conditions of the final application.

Supervisors Part Context

This device belongs to the TL7700 series of voltage supervisors from Texas Instruments. It serves as a dedicated power management IC designed to monitor supply rails and generate reset signals. The series includes variants with different packages and fixed thresholds, but this specific model offers adjustability via external components.

Supervisors Replacement Considerations

Compatible alternatives include TL7700P, TL7700PS, and TL7700PW from Texas Instruments. These parts share similar supervisory functions but may differ in package type or specific electrical characteristics. Verify pinout compatibility and threshold adjustability before substitution.
