8) At supply voltage increase up to Vbb= 5.6 V typ without charge pump, VOUT ≈Vbb - 2 V

9) While demagnetizing load inductance, dissipated energy in PROFET is EAS= ∫ VON(CL) * iL(t) dt, approx.

EAS= 1/2 * L * I2L * (VOVNO(CNL()C-LV) bb )

10) Requires 150 Ω resistor in GND connection. Reverse load current (through intrinsic drain-source diode) is normally limited by the

connected load.
