Battery Chargers Procurement Notes

Verify the exact part number MAX8903DETI+ against official Analog Devices documentation to ensure compatibility with your design. Confirm that the 28-TQFN package dimensions and pinout match your PCB layout. Check for any specific ordering suffixes or revisions that may affect electrical characteristics or packaging details before finalizing procurement.

Battery Chargers Selection Notes

Select this component when a high-current 2A Li-ion charger with USB interface is required. Ensure the application environment stays within the -40°C to +85°C operating temperature range. Verify that the 16V maximum supply voltage rating aligns with the system's power source capabilities. Consider the 28-TQFN footprint availability during the PCB design phase.

Battery Chargers Part Context

This component belongs to the MAX8903 family of battery chargers. It is distinct from other Maxim Integrated products like the MAX38903 LDO regulators or MAX9003 operational amplifiers, which serve different functions within the power management and signal processing domains. The MAX8903 specifically targets single-cell lithium-ion battery charging applications.

Battery Chargers Replacement Considerations

Consult official Analog Devices documentation for verified cross-reference part numbers. Do not assume functional equivalence with other battery chargers without verifying pinouts, electrical specifications, and thermal performance.
