Precautions on Application
(1)When applying the gate voltage VG from an external source, be sure to connect it via a resistor equal to or greater than RG=VG/0.02[ohm]. However, this resistance is unnecessary if you are connecting a charge pump output from a SMARTMOS product.
VG < 14[V] VG MPC17511 RG > VG/0.02[ohm] CG = 0.01[uF]

OPEN
(2)Switching from the state of active current loading to high-impedance mode, indactance load and P.C.B. layout may induce over maximum ratings to a power supply pin. Zener diode or capacitor at VM pin will protect kick back voltage(it depends on the indactance load). The schottky diode at output pin will also protect it.

(3)Connect a capacitor of sufficient capacitance between the power supply and ground pins. For all large-current paths, use sufficiently wide copper conductor patterns and route them in the shortest distance possible.
(4)When using SMARTMOS products in your circuit design, make sure they are fully protected against static charge.
