Notes:
1.    Exceeding the absolute maximum rating may damage the device.
2.    The device is not guaranteed to function outside its operating rating.
3.    Devices are ESD sensitive. Handling precautions recommended. Human body model, 1.5k& in series with 100pF.
4.    Specification for packaged product only.
5.    Circuit breaker trip threshold is verified by monitoring the TIMER pin as it switches from discharging to charging (current), and by the GATE output
voltage going low.
