Texas Instruments BQ24381 Overvoltage/Overcurrent Protection IC and Li+ Charger Front End Protection IC with LDO Mode, 7.1 OVP BQ24381DSGR

The BQ24381DSGR is an Overvoltage/Overcurrent Protection IC designed for Li-ion battery charger front-end applications. It features a maximum input voltage of 30 V and provides accurate battery overvoltage protection, ensuring the safety of Li-ion batteries during charging. The device continuously monitors both input and battery voltages, and it can handle load currents of up to 1.7 A. Key protective features include output short-circuit protection, thermal shutdown at temperatures exceeding 140¬8C, and soft-start and soft-stop functions to prevent inrush currents and voltage spikes. The BQ24381 operates in LDO mode, maintaining a regulated output voltage of 5 V. It is packaged in a compact 2 mm x 2 mm 8-pin WSON package, making it suitable for space-constrained applications such as smartphones, PDAs, and low-power handheld devices.
