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.

+150°C max junction temperature is intended for short periods of time to prevent shortening the lifetime. Operation close to +150°C junction may trigger the shutdown of

the device even before +150°C, since this number is specified as typical.

NOTES:

1. The maximum voltage rating for the VB pin under continuous operating conditions is 5.5V. All other pins are allowed to operate continuously at

the absolute maximum ratings.

Electrical Specifications

Typical values are tested at VIN = 5V and +25°C Ambient Temperature, maximum and minimum values are

guaranteed over the recommended operating conditions, unless otherwise noted.
