5V VOLTAGE
REGULATOR WITH WATCHDOG TIMER
The TA8000S TA8000F is an IC specially designed for automotive microcomputer systems. It produces an output voltage of 5 ± 0.25V without need for adjustment from its accurate reference voltage and amplifier circuit. At power-on, it outputs a reset signal to reset the system. It will also output a reset signal when the 5 V output voltage drops below 85% because of external disturbance or other problem. It also incorporates a watchdog timer for self-diagnosing the system. When the system malfunctions, the IC generates reset pulses intermittently to prevent the system from running away.
