Regulated to an average of 12.6 V during normal operation; UVLO(ON) ~5 V falling, UVLO(OFF) ~14 V rising, OVP threshold ~15.5 V. Recommended operating range 5.5 to 12 V, absolute max 20 V. |+| 2 | GND | power_in | Device ground / power return reference for all internal circuits. |+| 3 | NC | unconnected | No internal connection. Should be left floating or tied to GND during normal operation. |+| 4 | CS | input | Current-sense input for cycle-by-cycle current limiting. Over-current threshold Vth_oc ~575 mV, short-circuit protection threshold Vth_scp ~0.7 V, CS-floating protection threshold ~1.0 V. Includes internal 300 ns leading-edge blanking; absolute max -0.3 to 7 V. |+| 5 | C | output | Internal power BJT collector pin (paralleled with pins 6, 7, 8). Vceo 450 V, Vcbo 700 V, peak collector current 1.0 A. |+| 6 | C | output | Internal power BJT collector pin (paralleled with pins 5, 7, 8).
