HV9980 Features ► ► ► ► ► ► ► 3-Channel LED Array Driver IC Integrated 200V, 25Ω (typ.
) MOSFETs Programmable output current to 80mA per channel TTL compatible PWM dimming inputs 3-Phase synchronous operation Leading edge blanking Short circuit protection with skip mode Over-temperature protection illumination.
The output currents are programmed by controlling peak source current in each of the three internal 200V, 25Ω switching MOSFETs.
The peak current is detected by monitoring voltage at external sense resistors connected to RSENSE1-3.
The switching MOSFET is turned off when the corresponding current sense signal exceeds the reference voltage applied at REF1-3 (in the case of normal out...
