TL7757ILPE3 Equivalent & Substitute Parts
Part Overview
The TL7757ILPE3 is a power management integrated circuit (PMIC) supervisor designed for single-channel voltage monitoring and reset signal generation. This device operates as a simple reset/power-on reset controller with open drain or open collector output configuration, housed in a TO-92-3 through-hole package. The TL7757ILPE3 carries an obsolete product status, making identification of functionally equivalent alternatives essential for ongoing system support, maintenance, and component procurement strategies.

Substitute Part Grouping Explanation
Substitution eligibility for the TL7757ILPE3 is determined by strict parametric equivalence across the following critical criteria:
Mandatory Matching Parameters:
- Voltage threshold: 4.55V
- Number of voltages monitored: 1 channel
- Output type: Open Drain or Open Collector
- Reset logic: Active Low
- Reset timeout: 5µs Maximum Propagation Delay
- Operating temperature range: -40°C ~ 85°C (TA)
- Package / Case: TO-226-3, TO-92-3 (TO-226AA)
- Mounting type: Through Hole
The TL7757ILP meets all parametric requirements for direct substitution. Both parts share identical electrical specifications, thermal operating ranges, and physical packaging, differing only in product status designation.

Engineering Selection Recommendations
The TL7757ILP is the primary substitute for the obsolete TL7757ILPE3. Both parts are manufactured by Texas Instruments and maintain identical electrical and mechanical specifications. The TL7757ILP carries an active product status, ensuring ongoing availability and supply chain continuity. Both parts comply with ROHS3 requirements and carry equivalent regulatory classifications (ECCN: EAR99, HTSUS: 8542.39.0001).
For applications currently using the TL7757ILPE3, transition to the TL7757ILP provides full functional compatibility without circuit redesign or board-level modifications. The through-hole TO-92-3 package remains consistent across both variants, supporting direct socket replacement in existing designs.
Frequently Asked Questions (FAQ)
Q: Can the TL7757ILP directly replace the TL7757ILPE3 in existing circuits?
A: Yes. Both parts share identical voltage threshold (4.55V), output configuration (open drain/open collector), reset logic (active low), propagation delay (5µs maximum), operating temperature range (-40°C ~ 85°C), and TO-92-3 package specifications. No circuit modifications are required.
Q: What is the primary difference between these two part numbers?
A: The TL7757ILPE3 is classified as obsolete, while the TL7757ILP maintains active product status. All electrical and mechanical parameters are equivalent.
Q: Are both parts RoHS compliant?
A: Yes. Both the TL7757ILPE3 and TL7757ILP are ROHS3 compliant.
Q: Does the package type differ between these parts?
A: No. Both parts use the TO-226-3, TO-92-3 (TO-226AA) through-hole package configuration.
Q: What voltage threshold does this supervisor monitor?
A: The threshold is 4.55V for single-channel voltage monitoring with active-low reset output.
