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: T_J = T_C = T_A
Electrical Specifications V_DD = 5V, V_BOOST = 11V, I_LOAD = 200mA, V_ON = 15V, V_OFF = -5V, V_LOGIC = 2.5V, limits over -40°C to
+105°C temperature range, unless otherwise specified.
