CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation of the

device at these or any other conditions above those indicated in the operational sections of this specification is not implied.

IMPORTANT NOTE: All parameters having Min/Max specifications are guaranteed. Typical values are for information purposes only. Unless otherwise noted, all tests

are at the specified temperature and are pulsed tests, therefore: TJ = TC = TA

Electrical Specifications VDD = 5V, VBOOST = 11V, ILOAD = 200mA, VON = 15V, VOFF = -5V, VLOGIC = 2.5V, over temperature from

-40°C to 85°C, unless otherwise specified.
