Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLC7733MPWREP is determined by the following critical parameters:

• Functional Type: Single-channel voltage supervisor with reset/power-on reset capability
• Voltage Monitoring: Single voltage threshold monitoring
• Output Stage: Push-pull or open drain/open collector configurations are functionally compatible for reset signal generation
• Reset Polarity: Active high or active low reset capability
• Manufacturer: Texas Instruments (same manufacturer ensures design continuity and support)
• Compliance: ROHS3 compliance and MSL rating of 1 (Unlimited)
• Mounting: Surface mount technology with compatible package footprints

The TPS3760A012DYYR qualifies as a substitute based on shared functional classification, single-channel monitoring capability, compatible reset functionality, identical manufacturer, and matching compliance certifications. Differences in output configuration (open drain vs. totem pole), voltage threshold, reset timeout, and package form factor are secondary considerations that do not preclude substitution in applications where these variations are acceptable.

Parameter Comparison

Engineering Selection Recommendations

The TPS3760A012DYYR is available as an active product from Texas Instruments, providing supply chain continuity for applications currently using the TLC7733MPWREP. Both devices maintain ROHS3 compliance and MSL rating of 1 (Unlimited), ensuring equivalent environmental and handling requirements.

Selection of the TPS3760A012DYYR requires circuit-level evaluation of the following differences:

• Output Stage Compatibility: The TPS3760A012DYYR uses open drain/open collector output versus the totem pole configuration of the TLC7733MPWREP. Circuit designs must accommodate pull-up resistor requirements for open drain operation.
• Voltage Threshold Variation: The TPS3760A012DYYR monitors 0.8V threshold compared to 2.93V for the TLC7733MPWREP. Application voltage monitoring requirements must align with the substitute part's threshold specification.
• Reset Timeout Difference: The TPS3760A012DYYR specifies 100µs maximum reset timeout versus 1.1ms minimum for the TLC7733MPWREP. System reset timing requirements must be compatible with the faster timeout specification.
• Operating Temperature Range: The TPS3760A012DYYR operates from -40°C to 125°C (TJ) versus -55°C to 125°C (TA) for the TLC7733MPWREP. Applications requiring operation below -40°C require the original part.
• Package Form Factor: The TPS3760A012DYYR uses 14-SOT-23-THIN packaging versus 8-TSSOP for the TLC7733MPWREP. PCB layout modifications are required for package substitution.

Frequently Asked Questions (FAQ)

Q: Can the TPS3760A012DYYR directly replace the TLC7733MPWREP without circuit modifications?

A: Direct replacement without modifications is not recommended. The TPS3760A012DYYR requires open drain pull-up resistor implementation, operates with a different voltage threshold (0.8V vs. 2.93V), and uses a different package footprint (14-SOT-23-THIN vs. 8-TSSOP). Circuit redesign is necessary.

Q: What is the primary functional difference between these two supervisor ICs?

A: Both devices function as single-channel voltage supervisors with reset/power-on reset capability. The primary differences are output stage topology (totem pole vs. open drain), voltage threshold specification, and reset timeout characteristics. Functional substitution depends on application-specific requirements for these parameters.

Q: Are both parts compliant with the same environmental and regulatory standards?

A: Yes. Both the TLC7733MPWREP and TPS3760A012DYYR are ROHS3 compliant, carry MSL rating of 1 (Unlimited), and are REACH unaffected. Regulatory compliance is equivalent between the two parts.

Q: Why does the TPS3760A012DYYR have a lower voltage threshold than the TLC7733MPWREP?

A: The voltage threshold is a design parameter specific to each supervisor IC model. The TPS3760A012DYYR is designed for applications requiring 0.8V threshold monitoring, while the TLC7733MPWREP targets 2.93V threshold applications. These are distinct product variants within the Texas Instruments supervisor portfolio.

Q: What is the impact of the different reset timeout specifications?

A: The TLC7733MPWREP specifies 1.1ms minimum reset timeout, while the TPS3760A012DYYR specifies 100µs maximum. Applications requiring longer reset pulse duration must account for this difference. The TPS3760A012DYYR provides faster reset assertion, which may require system-level timing validation.

Q: Is the TPS3760A012DYYR suitable for applications requiring operation below -40°C?

A: No. The TPS3760A012DYYR operates from -40°C to 125°C (TJ), while the TLC7733MPWREP operates from -55°C to 125°C (TA). Applications requiring operation below -40°C must use the original TLC7733MPWREP or identify alternative supervisors with extended low-temperature specifications.
