TPS3513D Equivalent & Substitute Parts

Part Overview

The TPS3513D is a multi-voltage supervisor IC manufactured by Texas Instruments, designed for power management applications requiring monitoring of three independent voltage rails. This device features open drain or open collector output configuration with active low reset functionality and a 200ms minimum reset timeout. The TPS3513D is classified as Last Time Buy, indicating end-of-life status. Identifying equivalent and substitute parts is essential for design continuity, long-term supply chain planning, and ensuring system reliability in applications where the primary part becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the TPS3513D is determined by the following critical parameters:

Primary Substitution Criteria:

• Number of voltages monitored (3 channels required)
• Voltage threshold values (3.3V, 5V, 12V)
• Output configuration (Open Drain or Open Collector)
• Reset logic polarity (Active Low)
• Reset timeout specification (200ms Minimum)
• Package compatibility (14-SOIC form factor)
• Operating temperature range (-40°C ~ 85°C minimum)

Substitute Classification:

Parametric Equivalent: TPS3514D matches all electrical and mechanical parameters of the TPS3513D, including 3-channel voltage monitoring, identical threshold values, output configuration, reset characteristics, and 14-SOIC packaging. The primary distinction is packaging format (Tube vs. standard packaging).

Functional Alternative: TPS3808G01DBVR is a single-channel supervisor with adjustable/selectable voltage thresholds and reset timeout. This part represents a functional alternative for applications where single-channel monitoring is acceptable, though it does not provide the 3-channel capability of the TPS3513D.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Parametric Equivalent):

The TPS3514D is the recommended parametric equivalent for the TPS3513D. Both parts are manufactured by Texas Instruments and share identical electrical specifications, including 3-channel voltage monitoring at 3.3V, 5V, and 12V thresholds, active low reset logic with 200ms minimum timeout, and 14-SOIC packaging. Both parts are ROHS3 compliant with MSL 1 rating. The TPS3514D is also classified as Last Time Buy, indicating similar end-of-life status. Selection between these two parts should be based on packaging availability (standard vs. Tube format) and current inventory levels.

For Alternative Applications (Functional Alternative):

The TPS3808G01DBVR is classified as a functional alternative suitable only for applications requiring single-channel voltage monitoring. This part offers adjustable/selectable voltage thresholds and reset timeout, providing design flexibility for applications that do not require the 3-channel monitoring capability of the TPS3513D. The TPS3808G01DBVR features an extended operating temperature range (-40°C ~ 125°C) and is currently in Active product status, offering superior long-term availability. However, the SOT-23-6 package requires PCB layout modifications compared to the 14-SOIC form factor of the TPS3513D.

Compliance Considerations:

All three parts maintain ROHS3 compliance and MSL 1 moisture sensitivity rating, ensuring compatibility with standard manufacturing and storage processes. The TPS3808G01DBVR's Active product status provides extended supply chain support compared to the Last Time Buy status of both the TPS3513D and TPS3514D.

Frequently Asked Questions (FAQ)

Q: Can the TPS3514D be used as a direct replacement for the TPS3513D?

A: Yes. The TPS3514D is a parametric equivalent with identical electrical specifications, including 3-channel voltage monitoring at 3.3V, 5V, and 12V thresholds, active low reset logic, 200ms minimum reset timeout, and 14-SOIC packaging. The primary difference is packaging format (Tube). No circuit modifications are required.

Q: What are the key differences between the TPS3513D and TPS3808G01DBVR?

A: The TPS3808G01DBVR is a single-channel supervisor compared to the 3-channel capability of the TPS3513D. The TPS3808G01DBVR features adjustable/selectable voltage thresholds and reset timeout, whereas the TPS3513D has fixed thresholds at 3.3V, 5V, and 12V. The TPS3808G01DBVR uses SOT-23-6 packaging versus the 14-SOIC package of the TPS3513D, requiring PCB layout changes. The TPS3808G01DBVR is currently in Active product status, offering longer availability.

Q: Is the TPS3808G01DBVR suitable for applications requiring 3-channel monitoring?

A: No. The TPS3808G01DBVR monitors only a single voltage rail. Applications requiring simultaneous monitoring of three independent voltage channels must use the TPS3513D, TPS3514D, or equivalent 3-channel supervisor devices.

Q: Are all substitute parts RoHS compliant?

A: Yes. The TPS3513D, TPS3514D, and TPS3808G01DBVR are all ROHS3 compliant with MSL 1 moisture sensitivity rating, meeting standard environmental and manufacturing requirements.

Q: What is the impact of the Last Time Buy status on the TPS3513D and TPS3514D?

A: Last Time Buy status indicates that these parts are at end-of-life and will no longer be manufactured after a specified cutoff date. For long-term supply chain planning, the TPS3808G01DBVR's Active product status provides extended availability, though it is suitable only for single-channel applications.

Q: Can the TPS3513D and TPS3514D be used interchangeably in existing designs?

A: Yes, provided that packaging format compatibility is confirmed. Both parts are parametric equivalents with identical electrical specifications and 14-SOIC packaging. Verification of specific packaging requirements (standard vs. Tube) is necessary before substitution.
