Hi Keith,
The difference is latched vs cycle-by-cycle overcurrent protection.
LMG3410R070 provides 1) latched OCP option, by which the FET is shut off and held off until the fault is reset by either holding the IN pin low for more than 350 microseconds or removing power from VDD.
LMG3411R070 provides 2) cycle-by-cycle cycle-by-cycle OCP option. In this mode, the FET is also shut off when overcurrent happens, but the output fault signal will clear after the input PWM goes low. In the next cycle, the FET can turn on as normal. The cycle-by-cycle function can be used in cases where steady state operation current is below the OCP level but transient response can still reach high current, while the circuit operation cannot be paused. It also prevents the power stage from overheating by having overcurrent induced conduction loss.
Best Regards,
John
