概要

Description

BQ24079TRGTR is a TI single‑cell Li‑ion/Li‑polymer battery charger with integrated power‑path management. It accepts a USB or other suitable input and charges one cell while simultaneously supplying the system, via a regulated end voltage (4.2V) and a programmable charge current. Features include: constant‑current/constant‑voltage charging, automatic recharge, thermal regulation, and broad protections (overcurrent, short‑circuit, overvoltage, temperature). It also provides status outputs (e.g., CHG/STAT) to report charging state. The TRGTR suffix denotes a specific TI packaging/reel configuration for this part. Typical applications are portable devices (phones, wearables, cameras, etc.) that require simple, compact Li‑ion charging from USB. For exact electrical specs, programming options, and package details, consult the bq24079 datasheet and TI product page.

Features

BQ24079TRGTR features (highlights):
- Single-cell Li-Ion/Li-Po charger with USB/adaptor input (typical 5 V source)
- Programmable charge current up to about 1.5 A; constant-current/constant-voltage charging to 4.2 V
- Integrated power-path management to power the system while charging and prevent battery backflow
- Battery temperature monitoring via external NTC thermistor; safety shutoff if out of range
- Charge modes: pre-charge/trickle, fast charge, end-of-charge termination
- Robust protections: input OV, battery OV, short-circuit/OC protection, and thermal regulation
- Automatic recharge when battery falls below a threshold
- Status indicators (e.g., CHG/STAT) for charging and standby
- Suitable for compact, space-conscious designs; TRGTR package (tape-and-reel)
Note: exact electrical specs (current range, Vreg, thermal limits) are in the datasheet.

Package

BZ24079TRGTR is in a VQFN-20 (4x4 mm) package with exposed pad; RoHS/Green; Tape‑and‑Reel packaging.

Pinout

- Pin count: 16 pins (VQFN-16 type).
- Function: Highly integrated single-cell Li-Ion battery charger with power-path management. It charges the battery from USB/5V input, provides system load sharing, and uses a PROG resistor to set the charge current. Includes status/enable pins for signaling charge status and enabling/disabling charging.

Manufacturer

- Manufacturer: Texas Instruments Incorporated (TI).
- What kind of company: An American multinational semiconductor company that designs and manufactures analog, mixed-signal, and embedded processing integrated circuits.

Application

- USB or wall adapter powered single-cell Li‑ion/Li‑Pol battery charger
- Integrated power-path management to run the system while charging
- Suitable for compact, cost‑sensitive portable devices
Common applications: mobile phones, MP3 players, digital cameras, handheld scanners, wearables, wireless peripherals, and other compact consumer electronics.
