The BQ24045DSQR from Texas Instruments is a versatile standalone linear battery charger IC. It is specifically designed for single-cell Lithium Ion and Li-Polymer battery applications, supporting a charge current of up to 1A and a fixed charge voltage of 4.35V.
This IC features essential protection mechanisms including over-temperature, over-voltage, and short-circuit protection. It operates within a temperature range of 0°C to 125°C, making it suitable for various environmental conditions. The device also includes input voltage regulation (VINDPM) to maximize adapter power and battery temperature monitoring via a thermistor for JEITA profile compliance.
Packaged in a compact 10-WSON (2x2 mm) surface-mount package, the BQ24045DSQR is ideal for space-constrained designs. Its control interface is standalone and RC-settleable, simplifying integration into power management systems. The charger provides status indications for charging and charge completion.
