TA8000S

The TA8000S is an IC specially designed for automotive microcomputer systems which 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 5V 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.

The features of TA8000S can be summarized as (1)accurate output : 5±0.25V; (2)output voltage adjusting pin attached; (3)power-on reset timer incorporated; (4)watchdog timer incorporated; (5)wide operating voltage range : 40V; (6)operating temperature range : from -40 to 85; (7)load dump protection : 80V (1 second); (8)small SIP-9 pin:

The absolute maximum ratings of TA8000S are (1)input voltage VIV1, 80(1s)V/VIN2, - 5~+16V; (2)output current IOUT1/IOUT2: 10/4mA; (3)output voltage IOUT1/IOUT2: 80(1s)V/16V; (4)power dissipation PD: 500mW; (5)operating temperature Topr: -40~85°C; (6)storage temperature Tstg: -55~150°C; (7)lead temperature-time Tsol: 260 (10s)°C; (8)(Note) VIN1: BIAS input, VIN2; CK input, IOUT1, VOUT1: OUT output, IOUT2, VOUT2 : RESET output.
