The DIO8210H is used to drive a LED string, and remove the 100/120 Hz current ripple on AC/DC power by a capacitor between VC and GND. If the voltage on LED pin exceeds 6 V, the current ripple removing function is disabled, which could help limit the power dissipation on chip. The DIO8210H provides short protection, open protection and HOT-PLUG protection. The maximum LED current is internally limited at 0.5 A. The DIO8210H provides over thermal protection. When the OTP is trigged, the function of current ripple removing is shielded until the temperature drop to 130°C.
