The relation between the OFF time and the external resistor value is shown in the graph of

Figure 6. OFF time vs ROFF value. The value typically ranges from 10 μs to 150 μs.

Device protections

5.4.1

Overcurrent and short circuit protections

The device embeds a circuitry protecting each power MOSFET against the over load and short circuit conditions

(short to ground, short to VS and short between outputs).

When the overcurrent or the short circuit protection is triggered the power stage is disabled and the EN\FAULT

The power stage is kept disabled and the open drain MOSFET is kept ON until the EN\FAULT input falls below
