TLC7725QD Equivalent & Substitute Parts

Part Overview

The TLC7725QD is a supervisor integrated circuit from Texas Instruments designed for power management applications. It functions as a simple reset/power-on reset device with push-pull, totem pole output configuration, monitoring a single voltage channel. The device is currently in Last Time Buy status, indicating that new production has ceased and existing inventory is being cleared. This status necessitates identification of equivalent substitute components to ensure continued availability for new designs and production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLC7725QD is determined by the following critical parameters:

Functional Equivalence Criteria:

• Device type: Simple Reset/Power-On Reset supervisor
• Number of monitored voltage channels: 1
• Operating temperature range: -40°C ~ 125°C
• Regulatory compliance: ROHS3 Compliant, REACH Unaffected

Electrical Compatibility Considerations:

• Voltage threshold setting capability
• Output configuration (push-pull vs. open drain)
• Reset logic polarity (active high vs. active low)
• Reset timeout specifications

Physical Compatibility:

• Surface mount technology
• Package form factor and pin count

The TPS3760A012DYYR qualifies as a substitute based on shared functional classification, single-channel voltage monitoring, identical operating temperature range, and equivalent regulatory compliance. However, differences in output configuration, voltage threshold, reset logic, and package type require careful evaluation for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The TLC7725QD is designated Last Time Buy, indicating end-of-life status. The TPS3760A012DYYR maintains Active product status, ensuring continued availability and manufacturer support.

Regulatory Compliance: Both devices meet ROHS3 compliance and REACH unaffected status, satisfying environmental and regulatory requirements for equivalent applications.

Substitution Feasibility: Selection of TPS3760A012DYYR as a substitute requires verification of the following application-specific parameters:

• Voltage threshold requirement: TPS3760A012DYYR operates at 0.8V threshold versus TLC7725QD at 2.25V
• Output stage compatibility: TPS3760A012DYYR uses open drain/open collector output versus push-pull totem pole configuration
• Reset logic requirement: TPS3760A012DYYR supports active low reset only
• Reset timeout tolerance: TPS3760A012DYYR maximum 100µs versus TLC7725QD minimum 1.1ms
• Package footprint: Different package types (8-SOIC versus SOT-23-14 Thin) require PCB layout modification

Direct substitution is not recommended without circuit-level analysis of these parameter differences.

Frequently Asked Questions (FAQ)

Q: Can TPS3760A012DYYR directly replace TLC7725QD in existing designs?

A: Direct replacement requires verification of voltage threshold, output configuration, and reset logic requirements. The devices differ in these critical parameters and may require circuit modifications.

Q: What is the primary reason for seeking substitutes for TLC7725QD?

A: The TLC7725QD is in Last Time Buy status, meaning production has ended. TPS3760A012DYYR is an active product from the same manufacturer suitable for new designs.

Q: How do the output configurations differ between these devices?

A: TLC7725QD provides push-pull, totem pole output capable of sourcing and sinking current. TPS3760A012DYYR provides open drain or open collector output, requiring external pull-up resistors.

Q: Are the package types compatible?

A: No. TLC7725QD uses 8-SOIC packaging while TPS3760A012DYYR uses SOT-23-14 Thin packaging. PCB layout and footprint modifications are required.

Q: Do both devices meet the same regulatory standards?

A: Yes. Both devices are ROHS3 compliant and REACH unaffected, meeting equivalent environmental and regulatory requirements.

Q: What voltage threshold differences exist between these supervisors?

A: TLC7725QD monitors at 2.25V threshold, while TPS3760A012DYYR monitors at 0.8V threshold. Application voltage requirements determine which threshold is appropriate.

Q: How do reset timeout specifications compare?

A: TLC7725QD specifies 1.1ms minimum reset timeout, while TPS3760A012DYYR specifies 100µs maximum. These different timing characteristics may affect system reset behavior.
