The channels can be parallelized to reduce power dissipation. When connected to Vcc rail, four integrated catch diodes clamp the turn-off transients generated by inductive loads even with huge inductance; combined with proper external TVS connected to VCC or to GND the IC allows fast decay, too. Each channel is protected against overload or short circuit event: the intervention level can be set by an external resistor on ILIM pin . Built-in thermal shutdown protects the chip against overtemperature even in case of short-circuit. If enabled, the integrated cut-off protection features a non-dissipative protection in case of overload; it limits both the output average current value and, consequently, the device overheating. Cut-off delay/restart can be programmed by external resistors on CoD pin; it can be disabled by shorting CoD to GND.
