TL7702AID1/A

Supervisors Overview

The TL7702AID1/A is a single-channel supervisor IC manufactured by STMicroelectronics, designed for simple reset and power-on reset applications. It features an open-drain or open-collector output and supports both high-active and low-active reset signals. The device monitors a single voltage threshold of 2.53V with a maximum transmission delay of 1µs for reset timeout. It operates within a temperature range of -25°C to 85°C (TA) and is housed in an 8-SOIC package with a width of 3.90mm. This component is currently obsolete and no longer in production.

Supervisors Feature Summary

• Provides simple reset and power-on reset functionality for monitored voltage rails
• Configurable reset signal polarity supporting both high-active and low-active states
• Output stage utilizes open-drain or open-collector configuration for flexible interfacing

Supervisors Applications

• Embedded system power monitoring
• Microcontroller reset circuitry
• Portable electronic device power management

Supervisors Procurement Notes

This part number is officially discontinued and no longer manufactured by STMicroelectronics. Procurement should focus on verified replacement components from the same family or compatible alternatives. Verify that substitute parts meet the required electrical specifications, including the 2.53V threshold and 8-SOIC package dimensions, to ensure compatibility with existing designs.

Supervisors Selection Notes

Designers requiring this specific supervisor function must evaluate alternative sources as the original part is end-of-life. Key selection criteria for replacements include matching the 2.53V threshold voltage, ensuring the 8-SOIC footprint compatibility, and confirming support for the required operating temperature range of -25°C to 85°C. Cross-referencing datasheets for equivalent reset timing characteristics is essential for seamless integration.

Supervisors Part Context

The TL7702AID1/A belongs to the TL7700A series of voltage supervisors. These devices are engineered to provide reliable reset signals when supply voltages drop below specified thresholds. The series is characterized by low quiescent current and fast response times, making them suitable for battery-powered and space-constrained applications where precise voltage monitoring is critical for system stability.

Supervisors Replacement Considerations

Publicly confirmed substitutes include Texas Instruments parts such as TL7702ACD, TL7702ACDR, TL7702AID, and TL7702AIDR. These alternatives offer similar functional characteristics and pinouts, facilitating direct replacement in existing designs without significant circuit modifications.
