MAX8934BETI+T

Battery Chargers Overview

The MAX8934BETI+T is a dual-input linear battery charger IC from the Smart Power Selector series, designed for single-cell Li+/Li-Poly batteries. It operates within a supply voltage range of up to 6.6V and supports a maximum charging current of 1.5A at a battery pack voltage of 4.2V. The device features programmable constant-current charging controlled via an I2C interface. It includes advanced battery temperature monitoring compliant with JEITA recommendations and offers overvoltage fault protection. The component is housed in a 28-TQFN (4x4) package with exposed pad and functions across a temperature range of -40°C to +85°C.

Battery Chargers Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration against official documentation. Confirm that the MAX8934B variant matches the required electrical specifications for the target application. Ensure compatibility with the 28-TQFN footprint during PCB layout. Validate JEITA compliance requirements if thermal monitoring is critical. Check for any obsolescence notices or limited availability status directly from Analog Devices.

Battery Chargers Selection Notes

Select this component when dual-input power management and precise thermal regulation are required for single-cell applications. The I2C interface allows for flexible configuration of charging profiles. Consider the 1.5A current limit and 6.6V input range for system design constraints. The exposed pad package requires appropriate thermal management on the PCB. Verify that the operating temperature range meets environmental conditions.

Battery Chargers Part Context

The MAX8934BETI+T belongs to the MAX8934 family of dual-input linear chargers. This series integrates charge control and power path management in a compact form factor. The device simplifies design by combining USB and external adapter inputs into a unified power solution. It targets consumer electronics requiring efficient battery charging with minimal external components.

Battery Chargers Replacement Considerations

Consult official Analog Devices substitution guides for verified alternatives. Cross-reference pinout and electrical characteristics before considering other models. Generic replacements may lack the specific Smart Power Selector functionality or JEITA compliance.
