Notes:
(1) Guaranteed by design.
(2) Semtech’s SmartDriver? FET drive ? rst pulls DH high with a pull-up resistance of 10 Ω (typical) until LX = 1.5V (typical). At this point,
an additional pull-up device is activated, reducing the resistance to 2 Ω (typical). This negates the need for an external gate or boost
resistor.
