TLC7701IP Equivalent & Substitute Parts

Part Overview

The TLC7701IP 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 1.1V voltage threshold and 1.1ms minimum reset timeout. The TLC7701IP is classified as Last Time Buy, indicating end-of-life status. Identifying equivalent and substitute parts is necessary to ensure continued design support, maintain supply chain continuity, and access components with active manufacturing status.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLC7701IP is based on the following critical parameters that must align for functional equivalence:

• Manufacturer: Texas Instruments (maintaining OEM ecosystem compatibility)
• Category: Power Management (PMIC) with supervisor functionality
• Type: Simple Reset/Power-On Reset operation
• Number of Voltages Monitored: Single channel (1)
• Voltage Threshold Range: Compatible threshold voltage for reset detection
• Output Configuration: Functional output type capable of driving reset signals
• Reset Timeout: Timing specifications suitable for system reset requirements
• Operating Temperature: Temperature range meeting or exceeding application requirements
• Compliance: ROHS3 and REACH compliance maintained

The TPS3760A012DYYR qualifies as a substitute based on these parameters. While it differs in output type (Open Drain vs. Push-Pull), mounting technology (Surface Mount vs. Through Hole), and package form factor, it maintains functional equivalence in single-channel voltage monitoring, reset generation, and active product status.

Parameter Comparison

Engineering Selection Recommendations

The TPS3760A012DYYR is the manufacturer-recommended substitute for the TLC7701IP. Selection of this substitute is supported by the following factors:

• Product Status: The TPS3760A012DYYR maintains Active status, ensuring continued availability and manufacturing support, whereas the TLC7701IP is Last Time Buy.
• Compliance: Both devices maintain ROHS3 and REACH compliance, meeting regulatory requirements.
• Functional Equivalence: Both devices provide single-channel voltage monitoring and reset generation for power management applications.
• Temperature Range: The TPS3760A012DYYR extends the operating temperature range to -40°C ~ 125°C, providing broader thermal coverage.

Design integration requires evaluation of the following differences:

• Output Type Change: Transition from push-pull to open-drain output requires circuit-level adaptation, including pull-up resistor configuration.
• Voltage Threshold Difference: The 0.8V threshold of the TPS3760A012DYYR differs from the 1.1V threshold of the TLC7701IP; threshold voltage selection must align with system power supply monitoring requirements.
• Reset Timeout Specification: The TPS3760A012DYYR specifies 100µs maximum reset timeout versus 1.1ms minimum for the TLC7701IP; timing behavior differs and must be evaluated against system reset sequencing requirements.
• Package Migration: Transition from 8-DIP through-hole to SOT-23-14 surface-mount requires PCB layout redesign.

Frequently Asked Questions (FAQ)

Q: Can the TPS3760A012DYYR directly replace the TLC7701IP without circuit modifications?

A: No. While both devices provide single-channel voltage monitoring and reset functionality, the output type differs (open-drain vs. push-pull). Circuit modifications are required, including pull-up resistor implementation for the open-drain output. Additionally, the voltage threshold and reset timeout specifications differ and must be evaluated for system compatibility.

Q: What is the primary reason for substituting the TLC7701IP?

A: The TLC7701IP is classified as Last Time Buy, indicating end-of-life status. The TPS3760A012DYYR is the manufacturer-recommended active substitute, ensuring continued supply chain access and manufacturing support.

Q: How do the voltage thresholds differ between these devices?

A: The TLC7701IP monitors at 1.1V threshold, while the TPS3760A012DYYR monitors at 0.8V threshold. The threshold voltage determines the power supply voltage level at which reset is triggered. System design must account for this difference when selecting the appropriate substitute.

Q: What are the package differences, and do they affect functionality?

A: The TLC7701IP uses 8-DIP through-hole packaging, while the TPS3760A012DYYR uses SOT-23-14 surface-mount packaging. Package differences do not affect electrical functionality but require PCB layout redesign and different assembly processes.

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

A: The TPS3760A012DYYR supports active-low reset configuration only, whereas the TLC7701IP supports both active-high and active-low. System design must accommodate active-low reset operation when using the TPS3760A012DYYR.

Q: What is the significance of the reset timeout difference?

A: The TLC7701IP specifies 1.1ms minimum reset timeout, while the TPS3760A012DYYR specifies 100µs maximum reset timeout. Reset timeout defines the duration the reset signal remains asserted after voltage threshold detection. This difference affects system reset sequencing and must be evaluated for compatibility with processor and peripheral reset requirements.
