Housed in an 8-TSSOP package (0.173\", 4.40mm width) with surface-mount mounting, it fits into compact PCB layouts typical of portable equipment, backup power systems, and embedded chargers. The supply voltage maximum is 6V, so the IC itself runs from a regulated 5V rail or a single Li-ion cell — the external pass transistor and supply rail handle the higher battery-charge voltage. The operating temperature range is -20°C to 70°C (TA) — this covers most indoor and commercial equipment environments but not extended industrial or automotive under-hood duty.","metaTitle":"BQ24401PWRG4 Texas Instruments Battery Charger IC, 8-TSSOP","metaDescription":"Texas Instruments BQ24401PWRG4 multi-chemistry battery charge controller IC.
