The BQ24090DGQT from Texas Instruments is a compact, highly integrated linear battery charger designed for single-cell Li-ion and Li-Polymer battery applications. It is suitable for space-limited portable devices and can operate from either a USB port or an AC adapter.
Key electrical specifications include a maximum charge current of 1A, a battery pack voltage of 4.2V, and an input voltage range from 4.45V to 6.45V, with an absolute maximum of 12V. The device offers precise charging with 1% charge voltage accuracy and 10% charge current accuracy. It also features programmable termination and precharge thresholds, and pin-selectable USB input current limits of 100mA and 500mA.
For protection and reliability, the BQ24090DGQT includes features such as 6.6V overvoltage protection, input voltage dynamic power management, thermal regulation at 125°C, and thermal shutdown at 150°C. It also provides output short-circuit protection and ISET short detection. The charger supports operation over the JEITA range via a battery NTC thermistor for hot/cold profile management.
This device is available in a 10-pin HVSSOP or MSOP package, suitable for surface mount applications. The operating temperature range is from 0°C to 125°C.
