TA8007AS

The TA8007AS is a kind of IC specially designed for microcomputer systems which incorporates a highly accurate constant-voltage power supply (5±0.25V) and various system reset functions. It also has an over-voltage protection function and a current limiter. Since its standby current is as small as 1.2mA it can be connected directly to an automotive battery. For system reset, it monitors of VREG× 88% and has a watchdog timer which can self-diagnose the microcomputer system so that program runaway can be prevented.

The features of TA8007AS can be summarized as (1)accurate output: 5±0.25V (Ta=25°C); (2)low standby current: 1.2mA; (3)watchdog timer and power-on reset timer incorporated as well as reset and monitor outputs; (4)wide operating voltage range: 40V(MAX.); (5)wide operating temperature: -40~105°C; (6)small SIP-9pin.

The absolute maximum ratings of TA8007AS are (1)input voltage VIN1 BIAS, IS/VIN2 CK/VIN1 BIAS, IS/: 60(1s)/-5~VCC V; (2)output current IOUT1/IOUT2: 10/2 mA; (3)Output Voltage VOUT1/VOUT2: 60(1s)/16V; (4)power dissipation PD: 500mW; (5)operating temperature Topr: -40~105°C; (6)storage temperature Tstg: - 55~150°C; (7)lead temperature-time Tsol: 260 (10s)°C:
