TPS3828-33DBVT Equivalent & Substitute Parts

Part Overview

The TPS3828-33DBVT is a single-channel power supply supervisor IC manufactured by Texas Instruments, designed for power-on reset and system monitoring applications. This device features an open drain or open collector output configuration with a 2.93V threshold voltage and 120ms minimum reset timeout. The part is currently in Last Time Buy status, indicating end-of-life production. Identifying equivalent and substitute parts is necessary to ensure design continuity and maintain supply chain reliability for new production runs or design revisions.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TPS3828-33DBVT is determined by the following critical parameters:

Mandatory Matching Parameters:

• Voltage threshold: 2.93V
• Output configuration: Open Drain or Open Collector
• Reset logic: Active Low
• Package: SC-74A, SOT-753 (SOT-23-5)
• Mounting type: Surface Mount
• Number of channels monitored: 1

Allowable Variations:

• Reset timeout: Minimum 120ms or greater
• Operating temperature range: May extend beyond -40°C ~ 85°C
• Product status: Active or Last Time Buy (Obsolete parts acceptable for legacy designs)
• Packaging format: Cut Tape (CT), Digi-Reel®, or Tape & Reel (TR)

Substitute parts are grouped into two categories: parametric equivalents (identical electrical specifications and output type) and manufacturer-recommended alternatives (different output configuration requiring circuit design review).

Parameter Comparison

Engineering Selection Recommendations

Parametric Equivalents (Direct Substitutes):

TPS3828-33DBVR is the primary parametric equivalent. This part maintains identical electrical specifications, output configuration, and reset characteristics as the TPS3828-33DBVT. The key distinction is product status: TPS3828-33DBVR is Active, providing superior long-term supply chain availability compared to the Last Time Buy status of the original part. This part is recommended for new designs and production continuity.

TPS3828-33DBVTG4 is a parametric equivalent with identical specifications but carries Obsolete product status. This part is suitable only for legacy design maintenance where existing inventory exists and supply chain disruption is not a concern.

Extended Temperature Range Alternatives:

MAX6320PUK29CY+T and MAX6822SUK+T are manufacturer-recommended alternatives from Analog Devices Inc./Maxim Integrated. Both parts maintain the 2.93V threshold, open drain output, and active low reset logic. These parts offer extended operating temperature range (-40°C ~ 125°C) and longer reset timeout (140ms minimum), providing enhanced performance margins for demanding thermal environments. Both parts carry Active product status, ensuring reliable supply availability. MAX6822SUK+T is supplied in Tape & Reel format, while MAX6320PUK29CY+T is available in Cut Tape and Digi-Reel formats.

Output Configuration Alternative:

TPS3825-33DBVT is a manufacturer-recommended alternative with different output configuration (Push-Pull, Totem Pole) and reset logic (Active High). This part requires circuit design review and is not a direct pin-compatible substitute. Selection of this part is appropriate only when the application circuit is designed to accommodate push-pull output and active high reset signaling.

Frequently Asked Questions (FAQ)

Q: Can TPS3828-33DBVR be used as a direct replacement for TPS3828-33DBVT?

A: Yes. TPS3828-33DBVR is a parametric equivalent with identical voltage threshold (2.93V), output type (open drain/open collector), reset logic (active low), reset timeout (120ms minimum), and package (SC-74A, SOT-753). The only difference is product status; TPS3828-33DBVR is Active, providing better supply chain continuity.

Q: What is the difference between the Texas Instruments TPS3828 series and the Maxim MAX6822/MAX6320 alternatives?

A: Both device families meet the core electrical requirements (2.93V threshold, open drain output, active low reset). The Maxim parts offer extended operating temperature range (-40°C ~ 125°C versus -40°C ~ 85°C) and longer reset timeout (140ms minimum versus 120ms minimum). Both manufacturers' parts are ROHS3 compliant and MSL 1 rated. Selection depends on thermal environment requirements and supply chain preferences.

Q: Can TPS3825-33DBVT be used in place of TPS3828-33DBVT?

A: TPS3825-33DBVT is not a direct substitute. While both parts share the same 2.93V threshold and SC-74A package, the TPS3825 features push-pull output and active high reset logic, whereas the TPS3828 has open drain output and active low reset. Circuit design modifications are required to accommodate these differences. Use this part only if your application circuit is designed for push-pull output and active high reset signaling.

Q: What packaging formats are available for these substitute parts?

A: TPS3828-33DBVR, TPS3828-33DBVTG4, and MAX6320PUK29CY+T are available in Cut Tape (CT) and Digi-Reel® formats. MAX6822SUK+T is supplied in Tape & Reel (TR) format. All parts use the same SC-74A, SOT-753 package footprint and are suitable for surface mount assembly.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts (TPS3828-33DBVR, TPS3828-33DBVTG4, MAX6320PUK29CY+T, and MAX6822SUK+T) are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the compliance profile of the original TPS3828-33DBVT.
