Figure 5 shows the power dissipated in a typical SN75372 as a function of load capacitance and frequency. Average power dissipated by this driver is derived from the equation PT(AV) = PDC(AV) + PC(AV) = PS(AV) where PDC(AV) is the steady-state power dissipation with the output high or low, PC(AV) is the power level during charging or discharging of the load capacitance, and PS(AV) is the power dissipation during switching between the low and high levels. None of these include energy transferred to the load, and all are averaged over a full cycle. The power components per driver channel are tHL P t + PL t L PDC(AV) = H H T P C(AV) tLH [ C V2 f C PS(AV) = tH PLH t LH + PHL t HL T tL T = 1/f where the times are as defined in Figure 14. Figure 12. Output Voltage Waveform PL, PH, PLH, and PHL are the respective instantaneous levels of power dissipation, C is the load capacitance. VC is the voltage across the load capacitance during the charge cycle shown by the equation VC = VOH - VOL PS(AV) may be ignored for power calculations at low frequencies. In the following power calculation, both channels are operating under identical conditions: VOH =19.2 V and VOL = 0.15 V with VCC1 = 5 V, VCC2 = 20 V, VC = 19.05 V, C = 1000 pF, and the duty cycle = 60%. At 0.5 MHz, PS(AV) is negligible and can be ignored. When the output voltage is high, ICC2 is negligible and can be ignored.

The input impedance of a FET consists of a reverse biased PN junction that can be described as a large capacitance in parallel with a very high resistance. For this reason, the commonly used open-collector driver with a pullup resistor is not satisfactory for high-speed applications. In Figure 12(a), an IRF151 power MOSFET switching an inductive load is driven by an open-collector transistor driver with a 470- pullup resistor. The input capacitance (Ciss) specification for an IRF151 is 4000 pF maximum. The resulting long turn-on time due to the combination of Ciss and the pullup resistor is shown in Figure 12(b).

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. * POST OFFICE BOX 655303 DALLAS, TEXAS 75265 POST OFFICE BOX 1443 HOUSTON, TEXAS 77251-1443 * 3-9 PACKAGE OPTION ADDENDUM www.ti.com 19-Jun-2010 PACKAGING INFORMATION Orderable Device Status (1) Package Type Package Drawing Pins Package Qty Eco Plan (2) Lead/ Ball Finish MSL Peak Temp (3) Samples (Requires Login) SN75372D ACTIVE SOIC D 8 75 Green (RoHS & no Sb/Br) CU NIPDAU Level-1-260C-UNLIM Purchase Samples SN75372DG4 ACTIVE SOIC D 8 75 Green (RoHS & no Sb/Br) CU NIPDAU Level-1-260C-UNLIM Purchase Samples SN75372DR ACTIVE SOIC D 8 2500 Green (RoHS & no Sb/Br) CU NIPDAU Level-1-260C-UNLIM Contact TI Distributor or Sales Office SN75372DRE4 ACTIVE SOIC D 8 2500 Green (RoHS & no Sb/Br) CU NIPDAU Level-1-260C-UNLIM Contact TI Distributor or Sales Office SN75372DRG4 ACTIVE SOIC D 8 2500 Green (RoHS & no Sb/Br) CU NIPDAU Level-1-260C-UNLIM Contact TI Distributor or Sales Office SN75372P ACTIVE PDIP P 8 50 Pb-Free (RoHS) CU NIPDAU N / A for Pkg Type Contact TI Distributor or Sales Office SN75372PE4 ACTIVE PDIP P 8 50 Pb-Free (RoHS) CU NIPDAU N / A for Pkg Type Contact TI Distributor or Sales Office SN75372PSR ACTIVE SO PS 8 2000 Green (RoHS & no Sb/Br) CU NIPDAU Level-1-260C-UNLIM Purchase Samples SN75372PSRE4 ACTIVE SO PS 8 2000 Green (RoHS & no Sb/Br) CU NIPDAU Level-1-260C-UNLIM Purchase Samples SN75372PSRG4 ACTIVE SO PS 8 2000 Green (RoHS & no Sb/Br) CU NIPDAU Level-1-260C-UNLIM Purchase Samples (1) The marketing status values are defined as follows: ACTIVE: Product device recommended for new designs.
