Test Setup Using Cranking Simulator

The Texas Instruments HVAL068A automotive cranking simulator or the equivalent can be used to
evaluate the performance during cranking. The simulator can generate three different types of cranking
test pulses and supports up to 50W. For more detail information, please refer Automotive Cranking
Simulator User’s Guide SLVU984.

Quick Test Procedure

4.3.1

Start-Up

•

Set load current to 0A in CC mode and turn on the electronic load

•

Set power supply current limit to 14A

•

Turn on the power supply and increase the supply voltage slowly up to 12V

•

Increase the load current slowly up to 1.1A

•

Decrease the power supply voltage down to 3.2V

4.3.2

Shutdown

•

Turn off the load

•

Decrease the input voltage down to 0V

•

Turn on the electronic load and discharge output capacitor
