The BQ24202DGNR from Texas Instruments is a linear charge management IC specifically designed for single-cell Lithium-Ion and Li-Polymer batteries. It is ideal for applications requiring a current-limited charger, such as those using wall-mount transformers.
This IC integrates a powerFET capable of delivering 500mA charge current and features high-accuracy voltage regulation with 0.5% accuracy. It supports a battery pack voltage of 4.2V and includes programmable features for current and timer control. Fault protection is provided against over-temperature and short circuits.
The BQ24202DGNR is housed in a compact 8-pin HVSSOP package with surface mount capability. It operates within a wide temperature range of -40°C to 125°C (TJ), making it suitable for various environmental conditions. The device also includes battery insertion and removal detection, as well as charge termination by minimum current and time.
Additional features include a time-limited pre-conditioning phase for deeply discharged cells and a sleep mode for low-power consumption. A charge status output is available for LED indication or host processor interface, signaling charge-in-progress, completion, and faults. Optional temperature monitoring before and during charging is also supported.
