TDA4862G

The TDA4862G is excellent convenient for designing a preconverter in ballasts and switched mode power supplies with sinusoidal line current consumption and a power factor approaching unity. The TDA4862G is particularly economic and versatile. The features of S042P are: (1)IC for sinusoidal line-current consumption; (2)Power factor approaching 1; (3)Controls boost converter as an active harmonics filter; (4)Internal start-up with low current consumption; (5)Zero current detector for discontinuous operation mode; (6)High current totem pole gate driver; (7)Trimmed ± 1.4% internal reference; (8)Undervoltage lock-out with hysteresis; (9)Very low start-up current consumption.

The following is about the absolute maximum ratings of TDA4862G: (1)Supply voltage at VCC Pin 8: -0.3V min; (2)supply + Z-current VCC-GND Pin 8: 0mA min and 70mA max; (3)Current into GTDRV Pin 7: -400mA min and 500mA max; (4)Clamping current into GTDRV Pin 7: 100mA max; (5)Clamping current into GTDRV Pin 7: -100mA min.

The electrical characteristics of the TDA4862G are: (1)supply current, OFF: 75A typ and 200A max; (2)supply current, ON: 4A typ and 6A max; (3)supply current, dynamic: 4.2mA typ and 8mA max; (4)Vcc turn-ON threshold: 11V typ and 11.5V max; (5)Vcc turn-OFF threshold: 8.0V min and 8.5V typ; (6)Vcc turn-ON/OFF hysteresis: 1.8V min, 2.3V typ and 3.0V max; (7)Vcc clamp: 15V min, 17V typ and 18V max.
