The TPS65810/TPS65811 is a single-cell Li-Ion battery and power management IC from TI. It supports a maximum charging current of 1.5A and integrates 8-channel A/D sampling system parameters. It supports single conversion, peak detection or average operating modes, and has software and hardware reset functions. It can set system parameters and access system status using the I2C interface, support AC adapter and USB port charging, and have interrupt functions and programmable masking signals system status modification to host.
The TPS65810 and TPS65811 are highly integrated single‑cell Li‑Ion battery‑ and power‑management ICs. They combine a battery charger, multiple LDO regulators, buck converters, display drivers, system management, and an I²C host interface in a compact 8 × 8 mm QFN package.
The devices support up to 1.5 A charge current, feature nine integrated LDOs (six adjustable, two fixed, one RTC backup), two programmable buck converters, and various GPIO, PWM and LED drivers. Electrical characteristics, absolute‑maximum ratings, and recommended operating conditions are detailed throughout the document, along with mechanical data for the exposed thermal pad.
