• Surface mount package in 24-pin QFN format (4x4mm footprint)
• Operating temperature range: -40°C to 85°C
• RoHS3 compliance
• Supply voltage tolerance for 10V maximum input

Active Equivalent Identification: The BQ25601DRTWR meets all substitution criteria as an active product from Texas Instruments. This part maintains functional compatibility while offering enhanced specifications in battery chemistry support and fault protection capabilities.

Parameter Comparison

Engineering Selection Recommendations

The BQ25601DRTWR is the direct active equivalent for the obsolete BQ24260RGET. Selection is based on the following engineering criteria:

Product Status & Availability: The BQ25601DRTWR maintains active product status with 23,127 units in stock, ensuring supply chain continuity compared to the obsolete BQ24260RGET.

Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements.

Functional Compatibility: The BQ25601DRTWR preserves all critical operating parameters including 3A maximum charge current, I2C interface, and -40°C to 85°C operating temperature range. The part supports expanded battery chemistry (Lithium Ion/Polymer) and higher supply voltage rating (14.6V vs. 10V), providing design margin without requiring circuit modifications.

Package Compatibility: Both parts use 24-pin QFN packages with 4x4mm footprint and exposed pad configuration, enabling direct PCB layout reuse.

Frequently Asked Questions (FAQ)

Q: Can the BQ25601DRTWR directly replace the BQ24260RGET on existing PCBs?

A: Yes. Both parts use identical 24-pin QFN (4x4mm) surface mount packages with exposed pad configuration. Pin assignments and I2C interface are compatible. No PCB redesign is required.

Q: What are the key differences between these parts?

A: The BQ25601DRTWR offers expanded battery chemistry support (Lithium Ion/Polymer vs. Lithium Ion only), higher maximum supply voltage rating (14.6V vs. 10V), enhanced fault protection (includes short-circuit detection), and programmable voltage control in addition to current control. The BQ25601DRTWR is an active product while the BQ24260RGET is obsolete.

Q: Are there any firmware or software changes required for substitution?

A: The I2C interface and programmable current control are preserved. Designs utilizing only current programmability require no changes. Designs that do not use voltage programmability on the BQ25601DRTWR are unaffected by the additional feature.

Q: What is the moisture sensitivity level difference?

A: The BQ24260RGET has MSL 2 (1 Year); the BQ25601DRTWR has MSL 1 (Unlimited). The BQ25601DRTWR offers superior moisture tolerance, reducing handling and storage constraints.

Q: Are both parts RoHS compliant?

A: Yes. Both the BQ24260RGET and BQ25601DRTWR are ROHS3 compliant and REACH unaffected.
