TA8005F

The TA8005F is a kind of IC specially designed for micro- computer systems which incorporates a highly accurate constant-voltage power supply (5±0.25V) and various system reset functions. For system reset, it monitors the output voltage of VREG×85% and has a watchdog timer which can self-diagnose the microcomputer system so that program runaway can be prevented. Since its bias current is as small as 1.4mA it can be connected directly to an automotive battery.

The features of TA8005F can be summarized as (1)accurate output : 5±0.25V; (2)low bias current : 1.4mA; (3)power-on reset timer incorporated; (4)watchdog timer incorporated; (5)wide operating voltage range: 40V; (6)operating temperature range: from -40 to 85°C; (7)output voltage adjusting pin attached; (8)small SIP-14 pin.

The absolute maximum ratings of TA8005F are (1)input voltage VIN1/VIN2: 60(1s)/-5~VCC V; (2)output current OUT1/OUT2: 10/4mA; (3)output voltage OUT1/OUT2: 60(1s)/16V; (4)power dissipation: 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.
