Product details

Single-cell Li-Ion power manager with I²C control

The TPS65022RHAT is a Texas Instruments power-management IC built for 1-cell Lithium Ion/Polymer battery applications. It integrates charging, regulation, and monitoring into a single 40-VQFN (6x6) Exposed Pad package, with an I²C interface for host-side parameter adjustment.

Active production – ordering and lifecycle

I²C interface and host integration

The I²C interface lets the system MCU read battery status, set charge current, and enable/disable outputs. This eliminates the need for separate ADC or GPIO lines for battery monitoring — the PMIC handles it on the serial bus.

Frequently asked questions

Is TPS65022RHAT obsolete?

No end-of-life notice or last-time-buy date is published.

What is the difference between TPS65022RHAT and TPS65022RHAR?

The suffix 'R' in TPS65022RHAR typically indicates a different reel or package quantity variant. The base die and function (Power Management, I²C, 1-cell Li-Ion) are identical. Confirm the reel quantity and tape orientation with the datasheet before ordering.

Is TPS65022RHAT compatible with 2-cell Li-ion batteries?

No — the TPS65022RHAT is designed for 1-cell Lithium Ion/Polymer packs. For multi-cell applications, consider the BQ79612PAPRQ1 (automotive-grade, SPI/UART, -40°C to 125°C) or the BQ2084DBT-V143 (2-4 cell, SMBus, -20°C to 85°C).
