manufacturer: description:for driving the n-channel gates, it is important to keep in mind that it is essentially like driving a capacitance to a sufficient voltage to get the channel fully on. driving the gates to 15 volts with respect to their sources assures that the transistors are on. this will keep the dissipation down to a minimum level. how quickly the gate gets turned on and off will determine the dissipation of the transistor while it is transitioning from off to on and vice-versa. turning the gate on and off too slow will cause excessive dissipation, while turning it on and off too fast will cause excessive switching noise in the system. it is important to have as low a driving impedance as practical for the size of the transistor. many motor drive ic's have sufficient gate drive capability for the msk 3020. if not, paralleled cmos standard gates will usually be sufficient. a series resistor in the gate circuit slows it down, but also suppresses any ringing caused by stray iductances in the mosfet circuit. the selection of the resistor is determined by how fast the mosfet wants to be switched. see figure 1 for circuit details. |
