TA8026P

TA8026P TOSHIBA BIPOLAR LINEAR INTEGRATED CIRCUIT SILICON MONOLITHIC TA8026P FLASHER CONTROLLER The TA8026P is designed as an automotive flasher controller. It can issue a rapied-flashing warning when a lamp failure occurs. It operates accurately in wide ranges of supply voltages and operating temperatures. It incorporates an accurate reference voltage circuit which compensates for lamp current characteristic variations due to supply voltage changes. FEATURES l Large output current : IOUT = 300mA (Max.) l Low standby current : ICC = 1.0mA (Typ.) l Reference voltage characterized by small temperature drift. Weight: 0.45 g (typ.) l Built-in circuit that compensates for variations in lamp voltage characteristics. l Output from combination of PNP and NPN transistors with suppression diode. l Wide operating temperature : Ta = −40 to 110°C l DIP-8pin. BLOCK DIAGRAM AND PIN LAYOUT 1 2002-02-27 PIN DESCRIPTION TA8026P PIN No. 1 2 3 4 5 6 7 8 SYMBOL GND VCC2 OUT CT RT VCC1 ST IN DESCRIPTION Grounded. Power supply pin (2). Open-emitter output of complementary combination of PNP and NPN transistors. A capacitor is connected between VCC and CT. This layout determines the flashing interval of the flasher. A resistor is connected between RT and CT. This layout determines the flashing interval of the flasher. Power supply pin (1). Current detection pin. The lamp current is detected through a shunt resistor connected between VCC1 and ST. Detection pin for lamp operation. ...
