Absolute Maximum Ratings
Absolute maximum ratings indicate sustained limits beyond which damage to the device may occur. All voltage param-
eters 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:
This IC contains a zener clamp structure between the chip V
and COM which has a nominal breakdown
CC
voltage of 15.6V. Please note that this supply pin should not be driven by a DC, low impedance power source
greater than the V specified in the Electrical Characteristics section.

Care should be taken to avoid output switching conditions where the V node flies inductively below ground by
more than 5V.
