Replacement verdict
Not a drop-in replacement
The MAX17262REWL+T and MAX17059X+T10 are not functionally interchangeable. The MAX17262REWL+T is a ModelGauge m5 fuel gauge with integrated current sensing, while the MAX17059X+T10 is a ModelGauge m3 fuel gauge requiring an external sense resistor. They differ in current-sense architecture, package footprint, communication interface, and battery chemistry support, so direct substitution is not feasible without hardware and firmware redesign.

Frequently asked questions
What are the primary differences between the MAX17262REWL+T and the MAX17059X+T10?
The MAX17262REWL+T is a low-power fuel gauge IC from Analog Devices (Maxim Integrated) featuring ModelGauge m5 EZ technology, while the MAX17059X+T10 is a ModelGauge m3 fuel gauge. The MAX17262REWL+T operates with a supply voltage range of 2.3 V to 4.9 V and supports I2C communication, whereas the MAX17059X+T10 operates from 2.5 V to 4.5 V and also uses I2C. The MAX17262REWL+T is available in a 9-bump WLP package, and the MAX17059X+T10 is offered in an 8-pin TDFN package. Both are designed for battery management in portable devices, but the MAX17262REWL+T includes advanced features such as SHA-256 authentication and dynamic power estimation.
Are the MAX17262REWL+T and MAX17059X+T10 pin-to-pin compatible?
No. The MAX17262REWL+T uses a 9-bump wafer-level package (WLP) with a 0.4 mm pitch, while the MAX17059X+T10 uses an 8-pin TDFN package with a 0.5 mm pitch. The pin counts, package dimensions, and land patterns differ, so they are not pin-to-pin compatible and cannot be directly substituted without PCB redesign.
Can the MAX17262REWL+T and MAX17059X+T10 be used interchangeably in a battery management design?
No. Although both are fuel gauge ICs, they differ in supply voltage range, package, communication protocol details, and feature set. The MAX17262REWL+T supports a wider supply voltage range (2.3 V to 4.9 V) and includes ModelGauge m5 EZ technology with SHA-256 authentication, while the MAX17059X+T10 operates from 2.5 V to 4.5 V and uses ModelGauge m3 technology. Interchangeability requires verifying all electrical and functional parameters against the specific design requirements and manufacturer datasheets.
What battery chemistries are supported by the MAX17262REWL+T and MAX17059X+T10?
Both devices are designed for lithium-ion (Li+) and lithium-polymer (Li-Po) batteries. The MAX17262REWL+T supports a wide range of battery capacities and is optimized for low-power applications, while the MAX17059X+T10 is also intended for Li+ batteries. For specific chemistry compatibility and configuration details, refer to the respective Analog Devices (Maxim Integrated) datasheets.
Do the MAX17262REWL+T and MAX17059X+T10 require external components for operation?
Yes. Both fuel gauge ICs require external components such as a sense resistor for current measurement and decoupling capacitors for the supply voltage. The MAX17262REWL+T typically uses a 5 mΩ to 10 mΩ sense resistor, while the MAX17059X+T10 also requires a sense resistor as specified in its datasheet. Additionally, pull-up resistors are needed for the I2C communication lines. The exact values and configurations should be taken from the respective manufacturer datasheets.
What is the operating temperature range for the MAX17262REWL+T and MAX17059X+T10?
The MAX17262REWL+T operates over a temperature range of -40°C to +85°C. The MAX17059X+T10 also operates over a temperature range of -40°C to +85°C. These ranges are specified in the respective Analog Devices (Maxim Integrated) datasheets and are suitable for most portable and industrial battery management applications.
Which device is better suited for low-power portable applications?
The MAX17262REWL+T is generally better suited for low-power portable applications due to its lower quiescent current and ModelGauge m5 EZ technology, which provides accurate state-of-charge estimation without requiring battery characterization. The MAX17059X+T10, while also suitable for portable applications, has a higher quiescent current and uses ModelGauge m3 technology. Designers should compare the specific power consumption and feature requirements against the target application.
Are the MAX17262REWL+T and MAX17059X+T10 RoHS compliant?
Yes. Both the MAX17262REWL+T and MAX17059X+T10 are RoHS-compliant and lead-free, as stated in their respective Analog Devices (Maxim Integrated) product pages and datasheets. The "+T" suffix in both part numbers indicates tape-and-reel packaging and RoHS compliance.
