BQ24295 Description

Short technical summary and product information.

The Texas Instruments BQ24295 is a highly integrated I2C controlled battery charger IC designed for 1-cell Li-Ion/Li-Polymer applications. It supports a wide input voltage range from 3.9V to 6.2V, with an absolute maximum rating of 15V. The charger can deliver a maximum charge current of 3A and features adjustable battery charge voltages between 3.5V and 4.44V.

Key electrical features include a synchronous boost converter for USB On-The-Go (OTG) functionality, providing an adjustable output voltage from 4.55V to 5.5V at up to 1.5A. The device operates with a switching frequency of 1.5MHz, enabling the use of small inductors. It offers high accuracy for charge voltage (±0.5%), charge current (±7%), input current (±7.5%), and boost output voltage (±3%) regulation.

Designed for flexibility, the BQ24295 integrates features like input current limiting (IINDPM), input over-voltage protection (OVP), and power path management. It supports USB D+/D- detection compatible with USB Battery Charger Spec (BC1.2) and can detect non-standard adapters. The operating temperature range is -40°C to 85°C, and it comes in a VQFN package measuring 16 mm² (4 mm × 4 mm).

This IC is suitable for applications requiring efficient battery charging and power management, with features like thermistor monitoring, IC thermal regulation, and instant system on capability with no battery or a deeply discharged battery.
