Texas Instruments TPS65800RTQR

Overview

TPS65800RTQR from Texas Instruments is a single-cell Li-ion battery and power-management IC integrating charge management, nine LDOs (six adjustable, two fixed 3.3 V, one 3.1 V RTC backup), two 600-mA programmable buck converters (SM1/SM2), RGB/white LED drivers, 8-channel ADC, I²C interface, and system sequencing logic in an 8×8 mm QFN-56 package. It targets handheld devices requiring compact, thermally robust power architecture with display and battery intelligence.

For engineers reviewing the TPS65800RTQR datasheet, TPS65800RTQR pinout, TPS65800RTQR application, or TPS65800RTQR equivalent, this page delivers verified specifications, validated pin functions, real-world use cases in smart phones and PDAs, and confirmed alternative options for supply continuity and design flexibility.

Technical Context

The TPS65800RTQR implements dual-input power path control with AC/USB prioritization, DPPM (Dynamic Power Path Management), thermal foldback, and pack temperature sensing via TS pin. Its integrated 8-channel ADC supports peak detection, averaging, and single-conversion modes for system parameter monitoring including battery voltage, temperature, and input status.

System sequencing is managed by internal logic with programmable delays (e.g., tDLY(D1) = 0.24–12 ms), POR masking, and dual reset (HOT_RST, RESPWRON). The I²C interface (400 kHz, standard-mode) enables full host control of output voltages, current limits, operating modes, and fault handling - while supporting stand-alone operation using default power-up states.

Key Specifications

Pinout & Package

TPS65800RTQR uses a thermally optimized 8×8 mm QFN-56 package with exposed thermal pad (GROUND PAD) connected internally to AGND0, AGND1, and AGND2. Pin numbering follows top-view layout per SLVS606C datasheet; all AGND pins are shorted internally to substrate and thermal pad, while PGND1/PGND2/PGND3 remain isolated.

FAQ

What is the maximum supported charge current for the TPS65800RTQR?

The TPS65800RTQR supports a maximum fast-charge current of 1500 mA, programmable via the ISET1 pin voltage and I2C scaling bits (100% scaling yields 2.500 V setpoint). Precharge current is separately configurable up to 150 mA. Thermal foldback and safety timers ensure safe operation under sustained high-current conditions.

Does the TPS65800RTQR support both AC adapter and USB charging inputs?

Yes, the TPS65800RTQR supports dual-input charging via dedicated AC and USB pins. It automatically selects the active source based on voltage thresholds (VIN(DT) = 190 mV), implements input current limiting (up to 2.75 A), and features independent dropout voltages (≤375 mV for AC, ≤45 mV for USB) to maintain system stability during source transitions.

How many LDOs does the TPS65800RTQR integrate, and what are their key characteristics?

The TPS65800RTQR integrates nine LDOs: six adjustable (LDO1/LDO2: 1.25–3.3 V, 150 mA; LDO3–LDO5: 1.224–4.46 V, 100 mA), two fixed 3.3 V (LDO0: 150 mA; LDO_PM: 20 mA), and one 3.1 V RTC backup (RTC_OUT: 8 mA). All support I2C programmability, soft-start, and ±3% output accuracy under load.

Can the TPS65800RTQR drive RGB LEDs and white LEDs simultaneously?

Yes, the TPS65800RTQR includes dedicated circuitry for both: an RGB LED driver with individual R/G/B brightness control and programmable flash period, plus a constant-current white LED driver capable of driving up to 6 LEDs in series with overvoltage protection. These operate independently and can be enabled concurrently without resource conflict.

What package type and thermal performance does the TPS65800RTQR use?

The TPS65800RTQR uses a 56-pin QFN package measuring 8 mm × 8 mm with an exposed thermal pad. Its thermal resistance θJA is 21.7 °C/W (JEDEC High-K board), supporting up to 3.22 W power dissipation at TA ≤ 55 °C, with derating of 0.046 W/°C above that temperature.
