On-chip fault protection covers over-temperature, over-voltage, and short-circuit conditions, which means the BOM can skip a separate charger front-end protector for many designs. ## Supply voltage and battery pack compatibility Maximum supply voltage is 10 V, so the part can be powered from a standard USB bus or a wall adapter without a pre-regulator. The battery pack voltage is specified at 3.7 V. ## Package and thermal design note","metaTitle":"BQ24278RGET Texas Instruments Li-Ion Battery Charger IC","metaDescription":"Texas Instruments BQ24278RGET single-cell Li-ion charger in 24-VQFN. 2.5A max charge current, -40°C to 85°C, integrated OVP/OTP/SCP.
