ROHS3 compliant, so no RoHS exemption expiry to manage for EU-market equipment. The protection set covers the three failure modes that dominate Li-ion pack field returns: overcurrent (short-circuit or excessive load), overtemperature (thermal runaway prevention), and over/under-voltage (cell imbalance or charger fault).","metaTitle":"TI BQ7790400PW Battery Protection IC, 3-4S Li-Ion, 20-TSSOP","metaDescription":"Texas Instruments BQ7790400PW battery protection IC for 3-4 series Li-ion packs.
