TA8000F

The TA8000F is a kind of IC specially designed for micro-computer 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 TA8000F 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(max); (6)operating temperature range: from -40 to 85°C; (7)load dump protection: 80V(max)(1 second); (8)SOP-14 pin.

The absolute maximum ratings of TA8000F are (1)input voltage VIN1/VIN2: 80(1s)/-5~16V; (2)output current OUT1/OUT2: 10/4mA; (3)output voltage OUT1/OUT2: 80(1s)/16V; (4)power dissipation: 280 mW; (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.
