Saving multi image file
The GUI does not support programming of *.mic files. The file will be programmed at ATE test if the volumes
are appropriate or by using the gang programmer for smaller sample and production runs.
7.1
Using the Multiple Config File Index Feature
Each separate PMIC configuration stored within the multiple config file can be accessed by a resistor connected
to the MTP pin.
The resistor must be connected from MTP to AGND (pin 50). The resistor must be decoupled with a 10 nF
capacitor (X7R type). The IRPS5401 will source 100
µ
A through the offset resistor for 1 ms immediately after
POR, the LSADC will measure the voltage drop on the resistor and the value will be latched into the digital core.
This happens one time at start up, so updating this resistor after POR will not affect the offset.
The table below shows the resistor value required to give the corresponding config file offset.
An 845 Ω resistor will give access to the config file programmed into the 1
st
segment, a 1.3 kΩ resistor will select
the 2
nd
segment, etc.
