Built-in reverse-current fault protection prevents the battery from discharging back through the charger when input power is removed — a design consideration for systems where the charger output stays connected to the battery bus during standby. ## Active status and compliance baseline The 6 V maximum supply voltage means the charger runs directly from a 5 V USB bus or a regulated 5 V rail without an additional buck converter — the input overvoltage margin is 1 V above the nominal 5 V.","metaTitle":"LP3918TLX/NOPB Texas Instruments Battery Charger IC, 950mA","metaDescription":"LP3918TLX/NOPB from Texas Instruments: Li-Ion battery charger IC, I²C interface, 950mA max charge current, 25-DSBGA package.
