Texas Instruments TPS65200YFFT

Overview

TPS65200YFFT from Texas Instruments is a highly integrated Li-ion battery charger IC with WLED boost driver and precision current shunt monitor, designed for space-constrained portable devices. It delivers up to 1.25-A fast-charge current, regulates charge voltage to ±0.5% at 25°C, supports I²C-programmable parameters (3.5–4.44 V, 150–1250 mA), and integrates synchronous 3-MHz PWM control with built-in power FETs for >90% efficiency in mobile phone battery management.

For engineers reviewing the TPS65200YFFT datasheet, TPS65200YFFT pinout, TPS65200YFFT application, or TPS65200YFFT equivalent, this device serves as a single-chip solution for USB/AC charging, white LED backlighting, and real-time battery current monitoring - requiring no external sense resistors below 20 mΩ and supporting D+/D− detection for OTG host negotiation.

Technical Context

The TPS65200YFFT implements a synchronous buck switching charger with programmable input current limiting (100/500/975 mA), dynamic power management (DPM) that adjusts charge current when input voltage drops below 4.2–4.76 V, and automatic transition between precharge (trickle), constant-current fast-charge, and constant-voltage termination phases. Its integrated current shunt monitor features 25 V/V fixed gain, ±40 µV typical input offset, and operates over –0.3 V to 7 V common-mode range.

The WLED boost converter operates at 600 kHz with 35-V open-LED protection, 200-mV reference accuracy (±2%), and supports PWM dimming up to 100 kHz. The I²C interface (400 kbps, 7-bit address 0x6A) enables full configuration of charge parameters, safety limits, and LED brightness - all within a single 36-ball DSBGA package measuring 2.6 mm × 2.9 mm.

FAQ

What is the maximum charge current supported by the TPS65200YFFT?

The TPS65200YFFT supports a maximum fast-charge current of 1250 mA when configured with appropriate external components and thermal management. This value is programmable via I²C register settings and depends on the selected sense resistor value (e.g., 20 mΩ) and input voltage conditions. The device also supports lower charge currents including 150 mA for trickle-charge mode, enabling flexible battery chemistry adaptation.

Does the TPS65200YFFT include USB On-The-Go (OTG) functionality?

Yes, the TPS65200YFFT integrates full USB OTG boost functionality. When enabled via the OTG pin or I²C register, it generates a regulated 5-V output (VBUS) from the battery (VSYS input range: 2.5 V to 4.5 V) with up to 200 mA output current. It includes cycle-by-cycle current limiting, overvoltage protection at 6.2 V, and automatic shutdown during fault conditions - all without requiring external MOSFETs or controllers.

How does the current shunt monitor in the TPS65200YFFT achieve high accuracy?

The TPS65200YFFT's current shunt monitor achieves high accuracy through a fixed 25 V/V gain, ±40 µV typical input offset voltage, and 100-dB common-mode rejection ratio. These specifications allow use of very low-value (down to 20 mΩ) external sense resistors while maintaining sub-1% current measurement error across temperature. The VZERO pin enables zero-current reference adjustment, and bidirectional output polarity (VSHNT relative to VZERO) supports both charge and discharge monitoring.

Can the TPS65200YFFT drive more than eight white LEDs?

No, the TPS65200YFFT's WLED boost converter is specified for up to eight series-connected white LEDs, with 35-V open-LED protection threshold ensuring safe operation under open-circuit conditions. Attempting to drive more than eight LEDs exceeds the 35-V output limit and risks triggering overvoltage protection or damaging the internal power switch. For higher LED counts, a dedicated high-voltage boost IC such as the TPS61165 is recommended.

What package type and dimensions does the TPS65200YFFT use?

The TPS65200YFFT uses a 36-ball, 0.4-mm pitch DSBGA (Die Size Ball Grid Array) package designated YFF, with nominal body dimensions of 2.6 mm × 2.9 mm. This ultra-compact footprint is optimized for thin-profile portable electronics and requires careful attention to solder paste volume and reflow profile due to its fine-pitch construction and thermal pad grounding requirements.
