Detailed Description

Single‑cell Li‑ion/Li‑poly switch‑mode battery charge management IC with integrated power‑path, I2C control, USB BC1.2 D+/D– detection, and boost (OTG) function. High‑efficiency synchronous buck charger for 1‑cell packs, optimized for USB adapters and wall adapters. Main Category: Integrated Circuits (ICs). Small Classification: Specialized ICs.

Key Features

1‑cell Li‑ion/Li‑poly charger with integrated MOSFETs and power‑path management

I2C programmable charge parameters and status reporting

High‑efficiency synchronous buck charging, typically around 1.5 MHz switching

Wide input range for USB/wall adapters (USB BC1.2 detection supported)

Adjustable fast‑charge current (high current capability for rapid charging)

Battery temperature monitoring via NTC (TS pin) with JEITA guidance

USB OTG boost: steps up battery to 5 V to power USB peripherals

System power‑path prioritizes system load while safely charging the battery

Safety timers, input current limiting, and robust fault protections

Low quiescent current and automatic power‑source selection

Key Advantages

Fast, efficient charging with less heat due to synchronous buck topology

True power‑path lets the system run immediately even with a deeply discharged or missing battery

Flexible software configuration via I2C for easy optimization across products

Built‑in USB compliance and OTG reduce external components and cost

Strong protection set (OVP, OCP, thermal regulation, safety timers) increases reliability

Small 4 x 4 mm footprint helps shrink portable designs

Packaging

Package type: 24‑pin VQFN (TI package code RGE), plastic molding, lead‑free, RoHS compliant

Body size: approx. 4.0 mm x 4.0 mm, low profile

Pin configuration: 24 perimeter pins with an exposed thermal pad on the underside

Pitch: typically 0.5 mm (verify exact value in the datasheet)

Thermal characteristics: exposed pad improves heat spreading; proper PCB thermal vias recommended

Electrical properties (high level): single‑cell charger, wide input voltage for USB/adapter use, high programmable charge current, I2C digital interface; confirm absolute ratings and limits in the datasheet

Shipment form: standard tape‑and‑reel for automated assembly (cut‑tape available by request)

Moisture sensitivity: follow MSL and baking guidelines in the TI datasheet/label

Operating temperature: typically −40°C to +85°C (check datasheet for the exact grade)

Lifecycle

Status: Active, widely used and supported by the manufacturer; not nearing discontinuation to the best of public knowledge

Equivalent/alternative models (verify pin/software compatibility in the datasheets):

- BQ24195, BQ24195L (same family, similar features and footprint)

- BQ24192, BQ24192I (lower current variants with I2C)

- BQ24197 (family variant; feature set differs)

- Newer‑generation options: BQ25895/BQ25890 series (higher integration and current; different compatibility)

- Orderable suffix alternatives of the same device: BQ24196RGER (tape‑and‑reel), BQ24196RGET (cut‑tape)
