KA7522D

The KA7522D is a kind of electronic ballast controller for fluorescent inverter systems. It includes whole function in KA7521, current feed back and preheating time controlled by temperature sensing.

There are some features of KA7522D as follows: (1)3-step soft start; (2)input voltage limit and brown out; (3)non lamp detect and lamp reset; (4)ZVS guard control; (5)current feedback control; (6)preheating time controlled by temperature sensing.

The following is about the absolute maximum ratings of KA7522D (Ta=25, unless otherwise specified): (1)supply voltage, VCC: 20 V; (2)peak driver output current, IO(P): 500 mA; (3)operating ambient temperature, TOPR: -20 to +100; (4)storage temperature, TSTG: -65 to +150.
