Article doubling ADN8810 Iout configuration query (SR#: 1202803)

Q 

When configuring two ADN8810 devices for Iout >300mA, cause Iout fluctuates.

 

A 

For Iout >300mA.  Design and connect as shown in fig. 18 of datasheet rev.A
(i.e. parallel them up) with track as short and of equal distance from these
IC's. to avoid spi writing i.e. race hazard, hence sometime you get the info
written to, sometime you don't. Also make sure your components such as resistor
etc. have very good tolerances (<= 1%).
