BQ25703ARSNR Description

Short technical summary and product information.

The BQ25703ARSNR from Texas Instruments is a versatile battery charge controller IC designed for 1 to 4 cell battery configurations. It operates with an input voltage range of 3.5V to 24V and supports multi-chemistry battery types including Lead Acid, Li-Ion/Li-Polymer, Lithium Phosphate/LiFePO4, NiCd, NiMH, and SuperCap.

 

This device features an I2C interface for control and status reporting, enabling flexible system configuration. Key electrical specifications include a maximum charge current of 8.128A and a maximum input voltage of 30V. It incorporates features like IC thermal regulation, input current optimization (ICO), input current limit (IINDPM), input over-voltage protection (OVP), an integrated ADC, and power path management.

 

The BQ25703ARSNR supports seamless transition between buck and boost operations and provides input current and voltage regulation against source overload. It also includes system power monitoring for CPU throttling and a comprehensive PROCHOT profile. The controller is suitable for applications requiring USB Type-C and USB Power Delivery compatibility, as well as USB On-The-Go (OTG) functionality.

 

Packaged in a 32-QFN (4x4) with an exposed pad, the BQ25703ARSNR is designed for surface mount installation. It operates within an ambient temperature range of -40°C to 85°C.
