[A] Short-Circuit Protection (N-side only with the external shunt resistor and RC filter)
a1. Normal operation: MOSFET ON and outputs current.
a2. Short circuit current detection (SC trigger)
(It is recommended to set RC time constant 1.5~2.0μs so that MOSFET shut down within 2.0μs when SC.)
a3. All N-side MOSFET's gates are hard interrupted.
a4. All N-side MOSFETs turn OFF.
a5. FO outputs for tFo=minimum 20μs.
a6. Input = “L”: MOSFET OFF
a7. Fo finishes output, but MOSFETs don't turn on until inputting next ON signal (LH).
(MOSFET of each phase can return to normal state by inputting ON signal to each phase.)
a8. Normal operation: MOSFET ON and outputs current.

[B] Under-Voltage Protection (N-side, UV_D)
b1. Control supply voltage V D exceeds under voltage reset level (UVDr), but MOSFET turns ON by next ON signal (LH).
(MOSFET of each phase can return to normal state by inputting ON signal to each phase.)
b2. Normal operation: MOSFET ON and outputs current.
b3. VD level drops to under voltage trip level. (UVDt).
b4. All N-side MOSFETs turn OFF in spite of control input condition.
b5. Fo outputs for tFo=minimum 20μs, but output is extended during VD keeps below UVDr.
b6. VD level reaches UVDr.
b7. Normal operation: MOSFET ON and outputs current.
