Other Parts Discussed in Thread: TPS25942A
Hello
I'm using the TPS25944A as a power management device. I specifically chose the version TPS25944A to use the overcurrent shutdown mode. In the datasheet the following statement is noted:
" The TPS25942 limits current to the programmed I(LIM) level. TPS25944 does not limit current but runs the fault timer when I(LOAD) > I(LIM)." (SLVSCE9D –JUNE 2014–REVISED OCTOBER 2017, page 8, note (3))
In my application, I set I(LIM) to 1.1A. When I reduce the load resistance (potentiometer) to create overcurrent, the load-current will be limited to I(LIM) and the device does not shut off after 4ms.
Is there a further configuration to be done to use the overcurrent shutdown mode of this device?
Thanks in advance!
