概述

Description

BQ24012DRCR is TI’s highly integrated Li‑ion battery charger for a single-cell battery. It accepts a USB or 5V adapter input and provides a complete charging solution with power-path management, so the system can run from the input while the battery is charged.
Key points:
- 1‑cell Li‑ion/Li‑pol battery charging with constant-current/constant-voltage regulation, preconditioning, and end-of-charge termination.
- Power-path design to power the system while charging, reducing the need for a separate battery management stage.
- Built-in safety features: protection against overvoltage, overcurrent, thermal shutdown/regulation, and easy battery temperature monitoring via external sensing.
- Small package option (DRCR) suitable for compact portable devices.
- Typical use: USB-powered handheld devices, wearables, portable radios, USB power banks, and other single-cell battery-powered products.
In short, bq24012DRCR offers an efficient, safe, and compact charger solution for single-cell Li‑ion batteries with USB input.
