AUIPS6125R
Over Power Shut Down protection
The AUIPS6125R integrates an over-power protection in order to limit the thermal stress in the Mosfet during certain
conditions like under voltage or high frequency. This protection is activated only when the part turns ON.
The internal capacitor is discharge with an internal constant (Psd_rst).
Case 1:
Typical in low voltage condition with a short circuit on the output, the voltage on the Vcc pin will oscillate around the under
voltage protection and the output current may not reach the 'over-current shut down' threshold.
To prevent thermal stress of the device, the 'Over power shut down' protection will turn off the part after the time ‘Psd_UV'
and the part is latched off.
