Overview
The MAX17042G+T is a fuel gauge IC from the ModelGauge family, designed for single-cell lithium-ion or lithium-polymer batteries. It operates within a supply voltage range of 2.5 V to 4.5 V and features an I2C interface for system communication. The device is housed in an 8-TDFN-EP package measuring 2x2 mm. It supports an operating temperature range of -20°C to +70°C and includes a low standby current specification.
Feature Summary
- Implements ModelGauge mTech3 algorithm for accurate state-of-charge estimation without requiring battery characterization.
- Provides real-time monitoring of battery voltage, current, and temperature through integrated sensing capabilities.
- Features a compact surface-mount package with an exposed thermal pad for efficient heat dissipation.
Applications
- Smartphones and mobile phones
- Tablets and portable media players
- Medical devices
Procurement Notes
Verify the specific suffix 'G+T' against the manufacturer's official part numbering system to confirm package type and tape-and-reel specifications. Ensure compatibility with the required I2C address configuration and check for any regional distribution restrictions or limited availability status before finalizing procurement plans.
Selection Notes
Select this component when designing systems requiring high accuracy for single-cell lithium-based chemistries without extensive battery modeling. Consider the 8-TDFN package size constraints and the need for external pull-up resistors on the I2C lines. Evaluate the operating temperature range requirements against the specified -20°C to +70°C limit for the target application environment.
Part Context
This part belongs to the Maxim Integrated ModelGauge series of fuel gauges, which are widely used in portable electronics. It is functionally related to other parts in the MAX170xx family, such as the MAX17048, though package and specific feature sets may vary. The 'G' suffix typically denotes a specific package variant within the product line.
Replacement Considerations
Publicly confirmed substitute part numbers for the MAX17042G+T are not available in the provided documentation. Users should consult the manufacturer's official replacement guide or datasheet for qualified alternatives.
