TLC7733QP Equivalent & Substitute Parts

Part Overview

The TLC7733QP 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 TLC7733QP 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 TLC7733QP 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
• Operating temperature range – Must support -40°C to 125°C operation
• Compliance certifications – ROHS3 compliance and EAR99 ECCN classification maintained
• Output type compatibility – Push-pull totem pole output or equivalent active output configuration
• Threshold voltage range – Voltage monitoring threshold must be compatible with application requirements

The TPS3760A012DYYR qualifies as a substitute based on shared supervisor functionality, single-channel monitoring, compatible operating temperature range, and equivalent compliance status. However, differences in output configuration (open drain vs. totem pole), package type (surface mount vs. through hole), and threshold voltage (0.8V vs. 2.93V) require circuit-level evaluation for specific applications.

Parameter Comparison

Engineering Selection Recommendations

The TPS3760A012DYYR is designated as the manufacturer-recommended substitute for the TLC7733QP. Both devices maintain ROHS3 compliance and EAR99 ECCN classification, ensuring regulatory continuity. The TPS3760A012DYYR carries Active product status, providing long-term availability and supply chain stability compared to the Last Time Buy status of the TLC7733QP.

Selection between these devices must account for the following differences:

• Output stage difference – The TLC7733QP provides push-pull totem pole output; the TPS3760A012DYYR provides open drain output. Circuit designs relying on push-pull drive capability require output stage redesign or external pull-up resistor configuration.
• Threshold voltage difference – The TLC7733QP monitors 2.93V; the TPS3760A012DYYR monitors 0.8V. Applications with specific voltage monitoring requirements must verify threshold compatibility or select alternative TPS3760 variants with matching threshold specifications.
• Package and mounting difference – The TLC7733QP uses through-hole 8-DIP packaging; the TPS3760A012DYYR uses surface-mount SOT-23-14 packaging. PCB layout and assembly process modifications are required.
• Reset timeout difference – The TLC7733QP specifies 1.1ms minimum reset timeout; the TPS3760A012DYYR specifies 100µs maximum. Applications with specific timing requirements must verify compatibility.

Frequently Asked Questions (FAQ)

Q: Can the TPS3760A012DYYR directly replace the TLC7733QP without circuit modifications?

A: Direct pin-for-pin replacement is not possible due to different package types (8-DIP through-hole vs. SOT-23-14 surface-mount) and different output configurations (push-pull totem pole vs. open drain). Circuit redesign is required.

Q: What is the primary difference in output configuration between these devices?

A: The TLC7733QP provides push-pull totem pole output, capable of actively driving both high and low logic states. The TPS3760A012DYYR provides open drain output, requiring external pull-up resistor for high-state operation. Open drain output is suitable for applications with pull-up resistor networks or multi-device bus configurations.

Q: Are the voltage threshold specifications compatible?

A: No. The TLC7733QP monitors 2.93V threshold; the TPS3760A012DYYR monitors 0.8V threshold. These are distinct monitoring points. Applications requiring 2.93V threshold monitoring must verify alternative TPS3760 variants or select different supervisor IC families with matching threshold specifications.

Q: What compliance certifications are maintained in the substitute part?

A: Both the TLC7733QP and TPS3760A012DYYR maintain ROHS3 compliance and EAR99 ECCN classification. REACH status is unaffected for both devices.

Q: Why is the TPS3760A012DYYR recommended despite differences?

A: The TPS3760A012DYYR is manufacturer-recommended as a substitute because it provides equivalent supervisor IC functionality, single-channel monitoring capability, compatible operating temperature range, and active product status. However, the differences in output type, threshold voltage, and package require application-specific evaluation before implementation.

Q: What is the significance of Last Time Buy status for the TLC7733QP?

A: Last Time Buy status indicates the TLC7733QP is end-of-life. No further production is planned. Existing inventory is available for final orders, but long-term supply is not guaranteed. Migration to active substitute parts is recommended for new designs and ongoing production.
