BQ25970 Description

Short technical summary and product information.

The BQ25970 from Texas Instruments is an 8A battery charging solution utilizing a 97% efficient switched-capacitor architecture. This design is optimized for a 50% duty cycle, allowing the cable current to be half the battery current, which reduces power loss and temperature rise.

 

This charger IC offers integrated programmable protection features for safe operation, including input and battery over-voltage and over-current protection, as well as battery and connector temperature monitoring. It also includes an integrated 12-bit analog-to-digital converter (ADC) for monitoring various parameters like bus voltage, output voltage, battery voltage, and current.

 

The BQ25970 supports an input voltage range of 3.2 V to 12 V and a battery charge voltage range of 3.5 V to 4.65 V. It operates within a temperature range of -40°C to 85°C and uses an I2C control interface. The device is available in a 56-pin DSBGA package with a body size of 3.00 mm x 3.20 mm.

 

Key applications for the BQ25970 include smartphones and tablet PCs, where its high efficiency and fast charging capabilities are beneficial.
