® TDA7475A ELECTRO-LUMINESCENT DISPLAY DRIVER INTERNAL CLOCK GENERATION STAND-BY FUNCTION VOLTAGE SET-UP CONVERSION FUNCTION ANTI-RADIATION TRAPEZOIDAL WAVE FOR E.L. DISPLAY DRIVING CONSTANT CURRENT CHARGE/DISCHARGE OF E.L. DISPLAY 2-STEP BRIGHTNESS CONTROL (NORMAL OR DIMMED LUMINANCE) PROTECTIONS WITH AUTOMATIC RESET: - COIL-SWITCHING MOS OVERCURRENT - CHIP OVERTEMPERATURE BCD OFF-LINE TECHNOLOGY PowerSO16 ORDERING NUMBER: TDA7475A DESCRIPTION The TDA7475 is a new BCD OFF-LINE technology device intended for EL display lighting in carradio applications. Time-extended luminance is achieved by driving the display with constant-cur- BLOCK DIAGRAM rent pulses, which will automatically compensate for the ageing-related capacitance loss by providing more elevated voltage pulses.
