TS4871
ABSOLUTE MAXIMUM RATINGS
1. All voltages values are measured with respect to the ground pin.
2. The magnitude of input signal must never exceed V
3. Device is protected in case of over temperature by a thermal shutdown active @ 150°C.
4. Exceeding the power derating curves during a long period, involves abnormal operating condition.
OPERATING CONDITIONS
1. This thermal resistance can be reduced with a suitable PCB layout (see Power Derating Curves Fig. 20)
2. When mounted on a 4 layers PCB
