TA8045BF

The TA8045BF is designed especially for microcomputer system in automobiles and is capable of providing output voltage 5±0.15V without any adjustment. This IC incorporates the system reset function, that is, low voltage reset and watchdog timer which can self- diagnose the microcomputer system so that program runaway can be prevented. This IC also has an over-voltage protection, current limiter and thermal protection to protect the IC from destruction caused of overstress and load accident. In addition, this IC has a low standby current function, so it can be connected directly to an automotive battery.

The features of TA8045BF can be summarized as (1)operating DC supply voltage range: 6~30V; (2)transient supply voltage: 60V(max.); (3)extremely low quiescient current in standby mode: 400A(max); (4)high accurate output voltage: 5±0.15V(3%); (5)output current capability: 50mA(MAX); (6)dropout voltage between VIN and Vout: 1V(lout=50mA); (7)on-chip system reset function: watchdog timer, power on reset timer, low voltage reset; (8)on-chip protective function: current limiter (100mA TYP.), over-voltage protection (28V TYP.), thermal protection (150°C TYP.); (9)wide operating temperature: -40~105°C(125°C); (10)compact package: plastic SSOP 16 pin package.

The absolute maximum ratings of TA8045BF are (1)supply voltage VIN VIN: 30(DC)/60(<1s)V; (2)input voltage VIN: CK/RESET, STBY, TC -5~5V/-0.3~5V; (3)input current iin, CK, STBY, TC: -5~5 mA; (4)output current IOUT VOUT/RESET 50/2 mA; (5)output voltage VOUT VOUT, RESET: 16V; (6)operation temperature Topr: -40~105°C; (7)junction temperature TJ: -40~150°C; (8)storage temperature Tstg: -40~105°C; (9)lead temperature time Tsol: 260 (1s)°C.
