TLC7733IP Equivalent & Substitute Parts

Part Overview

The TLC7733IP is a single-channel power management supervisor IC manufactured by Texas Instruments, designed for reset and power-on reset applications. This device operates as a push-pull, totem pole output supervisor with a 2.93V threshold voltage and 1.1ms minimum reset timeout. The TLC7733IP is classified as Last Time Buy, indicating end-of-life status. Identifying equivalent and substitute parts is necessary to ensure design continuity and maintain supply chain reliability for applications requiring supervisor functionality with comparable electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLC7733IP is determined by the following critical parameters:

• Single-channel voltage monitoring capability – The substitute must monitor one voltage threshold
• Supervisor IC classification – Reset/power-on reset functionality required
• Output type compatibility – Push-pull, totem pole output is the primary electrical interface
• Voltage threshold range – 2.93V threshold defines the application voltage domain
• Reset timeout specification – 1.1ms minimum reset timeout establishes timing requirements
• Operating temperature range – -40°C ~ 85°C defines thermal operating envelope
• Regulatory compliance – ROHS3 compliance and REACH unaffected status required

The TPS3760A012DYYR qualifies as a manufacturer-recommended substitute. While it employs open drain/open collector output architecture (differing from push-pull configuration), it maintains single-channel voltage monitoring, supervisor IC functionality, and operates within compatible temperature and compliance parameters. The substitute operates at -40°C ~ 125°C, providing extended thermal range. Package transition from 8-DIP through-hole to 14-SOT-23-THIN surface mount requires PCB redesign consideration.

Parameter Comparison

Engineering Selection Recommendations

The TPS3760A012DYYR is designated as the manufacturer-recommended substitute for the TLC7733IP. Both devices maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements. The TPS3760A012DYYR carries Active product status, ensuring continued availability and supply chain support, whereas the TLC7733IP is Last Time Buy.

Selection of the TPS3760A012DYYR requires evaluation of output stage compatibility. The transition from push-pull, totem pole output to open drain/open collector output necessitates circuit topology review. The extended operating temperature range (-40°C ~ 125°C versus -40°C ~ 85°C) provides thermal margin for demanding applications. Package migration from 8-DIP through-hole to 14-SOT-23-THIN surface mount requires PCB layout redesign and assembly process modification.

Frequently Asked Questions (FAQ)

Q: Can the TPS3760A012DYYR directly replace the TLC7733IP without circuit modification?

A: Direct pin-for-pin replacement is not possible due to package differences (8-DIP through-hole versus 14-SOT-23-THIN surface mount) and output stage architecture differences (push-pull, totem pole versus open drain/open collector). Circuit redesign is required.

Q: What are the key electrical differences between these supervisor ICs?

A: The primary differences are output configuration and reset timeout specifications. The TLC7733IP provides push-pull, totem pole output with 1.1ms minimum reset timeout. The TPS3760A012DYYR provides open drain/open collector output with 100µs maximum reset timeout. Both maintain single-channel voltage monitoring and supervisor IC functionality.

Q: Does the TPS3760A012DYYR support both active high and active low reset?

A: The TPS3760A012DYYR supports active low reset only, whereas the TLC7733IP supports both active high and active low reset configurations. Application reset logic requirements must be verified before substitution.

Q: Are there voltage threshold differences between these parts?

A: Yes. The TLC7733IP operates at 2.93V threshold voltage. The TPS3760A012DYYR operates at 0.8V threshold voltage. These threshold differences define the monitored voltage domain and must be evaluated for application compatibility.

Q: What is the impact of the package change from 8-DIP to SOT-23-14?

A: Package transition requires PCB redesign, including footprint modification, routing changes, and assembly process updates. Through-hole mounting is replaced with surface mount assembly, affecting manufacturing and rework procedures.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the TLC7733IP and TPS3760A012DYYR are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.
