HIP5011 Datasheet | Intersil

features ensure easy start-up. First, the supply currents stay below specification as the supply voltages ramp up; no unexpected surges occur that might perturb a soft-start or deplete a charge-pump. Second, any power-up sequence of the VCC, VIN , or PWM pins can be used without causing large currents. Third, the chip operates when VCC is greater than 2V so VCC can be created from a charge pump powered from VIN.
