TA8042F

The TA8042F is an IC specially designed for microcomputer systems. It features an accurate reference voltage of 5±0.15V and various system reset functions. The system reset includes a voltage monitor capable of switching between 4.6V and 4.2V and a watchdog timer for self-diagnosing the system, to prevent a system runaway. The protective functions include a reverse battery polarity, current limiter, and overheat protection. The low standby current of 1mA enables direct connection to a car battery.

The features of TA8042F can be summarized as (1)accurate output : 5V±0.15V; (2)output power transistor attached: current capacity 100mA(max); (3)low standby current : 1mA; (4)low input-output voltage : 0.6V(max); (5)protection functions : reverse battery polarity, overheat protection, current limiter; (6)reset functions: power-on reset (output timing switching), watchdog low voltage detection; (7)HSOP-20 pin power flat package.

The absolute maximum ratings of TA8042F are (1)input voltage VIN1/VIN2/VIN3/VIN4: 60(1s)-30(reverse battery)/-5~VREG/-0.3~VREG V; (2)output current ILOAD/IOUT2: 100/2 mA; (3)output voltage VOUT: VREG V; (4)power dissipation PD: 2W(when using 50×50×1.6mm, 50%, Cu board); (5)operating temperature Topr: -40~105°C; (6)storage temperature Tstg: - 55~150°C; (7)lead temperature-time Tsol: 260 (10s)°C.
