Product details
Overview
BQ24153YFFT from Texas Instruments is a fully integrated switch-mode single-cell Li-ion/Li-polymer battery charger IC with USB compliance, I²C programmability, and USB-OTG boost capability. It delivers up to 1.25 A charge current, ±0.5% voltage regulation accuracy at 25°C, and supports input current limiting at 100 mA or 500 mA via OTG pin or I²C. It is used in space-constrained mobile phones and handheld devices requiring fast, safe, and host-controlled charging.
For engineers reviewing the BQ24153YFFT datasheet, BQ24153YFFT pinout, BQ24153YFFT application, or BQ24153YFFT equivalent, key selection criteria include its 20-pin WCSP package, 3 MHz synchronous PWM operation, integrated power FETs, VIN-based DPM threshold (4.2–4.76 V), and dual-mode functionality (charge + OTG boost) - all critical for compact USB-powered portable designs.
Technical Context
The BQ24153YFFT implements a synchronous fixed-frequency PWM controller operating at 3 MHz with 0%–99.5% duty cycle, enabling high efficiency across wide input (4.0–6.0 V) and battery (2.5–4.5 V) voltage ranges. Its integrated power FETs support up to 1.25 A charge rate and 200 mA VBUS boost output at 5.05 V.
It features three operational modes: charge mode (conditioning → constant-current → constant-voltage), boost mode (battery-to-VBUS conversion), and high-impedance sleep mode. Charge termination uses user-programmable current thresholds (50–400 mA) and safety timer (32 s or 15 min), while thermal regulation begins at ~125°C junction temperature.

Pinout & Package
Package: 20-bump YFF WCSP (2.1 mm × 2.0 mm, 0.4 mm pitch), bottom-side solder bumps, thermal pad connected to PGND.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VBUS (A1, A2) | USB input / OTG output | Accepts 4–6 V USB supply; outputs regulated 5.05 V during boost mode; requires 1 µF ceramic bypass to PGND. |
| PMID (B1–B3) | Power mid-rail node | Connection between internal reverse-blocking and high-side FETs; bypass with ≥3.3 µF capacitor to PGND for stability. |
| SW (C1–C3) | Switch node | Drives external inductor; connects to BOOT capacitor; carries high di/dt switching current - requires tight layout. |
| STAT (C4) | Open-drain status indicator | Pulls low during active charge; emits 128-ms fault pulses; configurable via I²C EN_STAT bit. |
| SDA (B4), SCL (A4) | I²C bidirectional interface | Supports up to 3.4 Mbps; requires 10 kΩ pull-ups to 1.8 V VAUX rail for proper logic levels. |

| BOOT (A3) | High-side gate driver supply | Connects via 10 nF ceramic capacitor to SW; provides gate drive voltage for top N-FET in buck topology. |
Key Features
| Feature | Design Value |
|---|---|
| USB-friendly boot-up sequence | Ensures safe enumeration before enabling charge or boost, preventing bus overcurrent faults on host ports. |
| Input voltage-based DPM (VIN DPM) | Automatically reduces charge current when input voltage drops below programmable threshold (4.2–4.76 V), preserving system load operation. |
| Reverse leakage protection | Integrated reverse-blocking FET prevents battery discharge through VBUS when input is absent or low - no external diode needed. |
| Thermal regulation & shutdown | Reduces charge current above ~125°C (TCF) and shuts down at 165°C (TSHTDWN) with 10°C hysteresis for robust thermal management. |
| Bad adaptor detection | Rejects under-voltage sources (<3.6–4.0 V) using 30 ms deglitch and 100–200 mV hysteresis, avoiding unreliable charging. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar USB-compliant single-cell Li-ion charger applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BQ24156YFFT | Higher 1.55 A max charge current; 4.0–9.0 V input range; no OTG boost; SLRST pin for safety register reset. | Used where higher charge rate and wider input voltage (e.g., wall adapters) are needed, but OTG functionality is unnecessary. | Select BQ24156YFFT when USB OTG is not required and 500 mA input current is insufficient - but verify 9 V absolute max rating compatibility. |
| BQ24158YFFT | No battery detection at power-up; no OTG boost; different I²C address (0x6A vs. 0x6B); same 1.25 A charge current and 4–6 V input range. | Targeted at cost-sensitive designs omitting OTG and battery presence sensing - e.g., disposable or sealed consumer electronics. | Choose BQ24158YFFT only if OTG support and battery detect are excluded from system requirements - firmware must accommodate different I²C address. |
Compared with BQ24156YFFT and BQ24158YFFT, the BQ24153YFFT uniquely combines USB-OTG boost (5.05 V/200 mA), 100/500 mA selectable input limiting via OTG pin, and battery detection - making it the sole option among the three for dual-role portable devices needing host-controlled charging *and* peripheral power.

FAQ
What is the maximum charge current supported by the BQ24153YFFT?
The BQ24153YFFT supports a programmable maximum charge current of 1.25 A. This value is set via I²C register configuration and is achievable with appropriate external components - including a 68 mΩ current-sense resistor and 1 µH inductor - under recommended operating conditions (VBUS = 5 V, TJ ≤ 85°C). The IC also includes cycle-by-cycle current limiting at 1.8–3.0 A for fault protection.
Does the BQ24153YFFT support USB On-The-Go (OTG) functionality?
Yes, the BQ24153YFFT supports USB OTG via integrated boost mode operation. When enabled (via OTG pin or I²C), it converts battery voltage (2.5–4.5 V) to a regulated 5.05 V output on the VBUS pin, capable of supplying up to 200 mA. This eliminates the need for a separate boost converter in dual-role portable devices.
What package type and dimensions does the BQ24153YFFT use?
The BQ24153YFFT uses a 20-bump Wafer Chip Scale Package (WCSP) with YFF designation, measuring 2.1 mm × 2.0 mm and 0.4 mm pitch. It features bottom-side solder bumps and an exposed thermal pad connected internally to PGND - requiring precise stencil design and reflow profiling for reliable assembly.
How does the BQ24153YFFT handle input current limiting?
The BQ24153YFFT supports two input current limit settings: 100 mA and 500 mA. These are selected either by the OTG pin logic level (Low = 100 mA, High = 500 mA) or programmatically via I²C. Accuracy is ±5% across –40°C to 125°C, and the IC implements dynamic power management (VIN DPM) to reduce charge current if input voltage drops below the programmed threshold.
Can the BQ24153YFFT operate without a battery connected?
Yes, the BQ24153YFFT can power the system load directly from VBUS even without a battery - entering "power up system without battery" mode as specified in the datasheet. In this state, it regulates VBUS and supports boost mode if enabled, but charge-related functions (e.g., CC/CV, termination) are disabled until a valid battery is detected.
