Description
The AUIPS6121R is a fully protected four terminal high
side switch. It features current sensing, over-current, over-
temperature, ESD protection and drain to source active
clamp. Shutdown type of protection provides a good
reliability under short circuit condition. The Ifb pin provides
both an analog feedback during normal operation and a
digital flag when the part is in protection mode.

Current sensing accuracy

Ifb leakage
I offset
Iout1
Iout2 Iout
The current sensing is specified by measuring 3 points :
- Ifb1 for Iout1
- Ifb2 for Iout2
- Ifb leakage for Iout=0
The parameters in the datasheet are computed with the following formula :
Ratio = ( Iout2 Iout1 )/( Ifb2 Ifb1)
I offset = Ifb1 x Ratio Iout1
This allows the designer to evaluate the Ifb for any Iout value using :
Ifb = ( Iout + I offset ) / Ratio if Ifb>Ifb leakage
For some applications, a calibration is required. In that case, the accuracy of the system will depends on the variation of
the I offset and the ratio over the temperature range. The ratio variation is given by Ratio_Hot and Ratio_Cold specified in
page 4.
The Ioffset variation depends directly on the Rdson:
I offset@-40°C= I offset@25°C / 0.8
I offset@150°C= I offset@25°C / 1.9
Maximum Vcc voltage with short circuit protection
The maximum Vcc voltage with short circuit is the maximum voltage for which the part is able to protect itself under test
conditions representative of the application. 2 kind of short circuits are considered: terminal and load short circuit.
