9 / 11 page SN75372 DUAL MOSFET DRIVER SLLS025A – JULY 1986 3–9 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 APPLICATION INFORMATION A faster, more efficient drive circuit uses an active pullup as well as an active pulldown output configuration, referred to as a totem-pole output. The SN75372 driver provides the high speed, totem-pole drive desired in an application of this type, see Figure 13(a). The resulting faster switching speeds are shown in Figure 13(b). 5 V TLC555P 1/2 SN75372 M t – Time – µs (b) (a) IRF151 48 V 4 3 2 1 0 0 0.5 1 1.5 2 2.5 3 7 48 3 5 1 2 6 Figure 14. Power MOSFET Drive Using SN75372 Power MOSFET drivers must be capable of supplying high peak currents to achieve fast switching speeds as shown by the equation I pk + VC tr where C is the capacitive load, and tr is the desired drive time. V is the voltage that the capacitance is charged to. In the circuit shown in Figure 13(a), V is found by the equation V = VOH – VOL Peak current required to maintain a rise time of 100 ns in the circuit of Figure 13(a) is I PK + (3 * 0)4(10*9) 100(10*9) + 120 mA Circuit capacitance can be ignored because it is very small compared to the input capacitance of the IRF151. With a VCC of 5 V, and assuming worst-cast conditions, the gate drive voltage is 3 V. For applications in which the full voltage of VCC2 must be supplied to the MOSFET gate, the SN75374 quad MOSFET driver should be used. |
