Since it is connected to VCC outside the IC, influence of output on / off on the detection voltage is low so that failure involving four lamps and other f
TA8021S TOSHIBA BIPOLAR DIGITAL INTEGRATED CIRCUIT SILICON MONOLITHIC TA8021S TRIPLE VOLTAGE SENSOR The TA8021S is an IC designed for automotive lamp failure detection.
When a lamp failure occurs, it detects the resulting lamp current change from the voltage across the detection resistor RS.
It has a reference voltage characterized by high accuracy and small temperature drift as well as a voltage comparator.
It is also designed to compensate for lamp current changes due to supply voltage varia
