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 variations.
It consists of three circuits which are supplied with power from
separate pins.
