APPLICATION NOTE

Startup Behavior L9903/L9904

Introduction
Purpose of the Application Note is to detail the startup behaviour of L9903 and L9904 devices and to
explain a correct initialization sequence, possibly being necessary when application configuration is
different from the one suggested inside datasheet.
In fact, in case an additional, external diagnostic structure is used, it may happen that after a first
connection of the supply voltage, and before first enabling of the device, the measurement results of
these diagnostic structure is not precise.
