TPS65811RTQT Description

Short technical summary and product information.

The TPS65811RTQT from Texas Instruments is a highly integrated Power Management IC (PMIC) designed for single-cell Lithium-Ion or Li-Polymer battery-powered devices. This device offers a comprehensive solution for power management needs, including a complete charge management system with thermal foldback and dynamic power management.

 

Key features include a total of 9 integrated LDOs (6 adjustable, 2 fixed at 3.3V, and 1 RTC backup at 1.5V) and 2 programmable DC-DC buck converters capable of 750 mA. It supports a wide supply voltage range of 4.35 V to 16.5 V and operates within an industrial temperature range of -40°C to 85°C.

 

The TPS65811RTQT facilitates system control and status monitoring through its I2C and USB host interfaces. It also includes 3 GPIO ports, programmable as drivers, A/D triggers, or buck converters, and 2 open-drain PWM outputs for controlling peripherals like backlights or vibrators. Display functions are supported by an RGB LED driver and a white LED driver with programmable current and brightness control.

 

Packaged in a 56-QFN (8x8) surface-mount form factor, the TPS65811RTQT is suitable for space-constrained applications. Its high level of integration helps reduce board area compared to discrete solutions, making it ideal for portable electronics such as PDAs, smartphones, MP3 players, and other handheld devices.
