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.

The recommended value for ROFF is in the range between 5 kΩ kΩ

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

input is forced low through the integrated open drain MOSFET discharging the external CEN capacitor.

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

the VRELEASE threshold, then the CEN capacitor is charged through the external REN resistor.
