Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the component may occur. Operating Ratings are conditions under which operation of

the device is guaranteed. Operating Ratings do not imply guaranteed performance limits. For guaranteed performance limits and associated test conditions, see the

Electrical Characteristics tables.

Note 2: All voltages are with respect to the potential at the GND pin.

Note 3: Voltage on the SD-BRGT pin should not exceed 6V.
