BQ27Z561YPHR Description

Short technical summary and product information.

The Texas Instruments BQ27Z561YPHR is a single-cell fuel gauge IC designed for Lithium Ion and Lithium Polymer battery packs. It integrates the Impedance Track algorithm for accurate state-of-charge reporting and includes SHA-256 authentication for battery pack security.

 

The device supports a wide battery capacity range from 100 mAh to 32000 mAh and operates with a low supply voltage down to 2 V. It communicates via HDQ or I2C interfaces at up to 400 kHz. The IC features a high-accuracy coulomb counter with less than 1 µV typical input offset error and supports current sense resistors down to 1 mΩ.

 

Power management includes multiple low-power modes: typical SLEEP mode current under 11 µA, DEEP SLEEP mode under 9 µA, and OFF mode under 1.9 µA. The device is rated for an operating temperature range of -40°C to 85°C.

 

The BQ27Z561YPHR is offered in a 12-DSBGA package measuring 1.68 mm x 2.05 mm for surface mount assembly.
