Absolute Maximum Ratings
Absolute maximum ratings indicate sustained limits beyond which damage to the device may occur. All voltage parameters
are absolute voltages referenced to COM, all currents are defined positive into any lead. The thermal resistance and power
dissipation ratings are measured under board mounted and still air conditions.

Note 1:
Note 2:
This IC contains a zener clamp structure between the chip VCC and COM which has a nominal breakdown
voltage of 15.6V. Please note that this supply pin should not be driven by a DC, low impedance power source
greater than the VCLAMP specified in the Electrical Characteristics section.
Enough current should be supplied into the VCC pin to keep the internal 15.6V zener clamp diode on this pin
regulating its voltage, VCLAMP.
