12 V Automotive LED synchronous H-Bridge topology with LITIX™ Power controller TLD5191ES
Application Circuit: Short circuit to GND - transient

- Change simulation time:
"Analysis->Transient: Start - End Display"
- Double click on the green window to enter design criteria
- Click on "Run" and Simulate Transient

This test bench shows the short circuit to ground detection and protection.
The fault is applied at 2.5 ms and released at 15 ms. During this time interval, the device will initiate the retry strategy
using the SOFT_START pin.

Notes:
BODY_DIODE is not a real diode but a Voltage Controlled Current Source which models the threshold and ON/OFF states resistance.
For correct functioning of the controller, the simulation maximum time step cannot exceed 150 ns. Values above this limit affect the internal
clock generation.
