Current Waveform Spike Suppression + – 5.0V Ref + – S R Q 7(11) 6(10) 5(8) 3(5) RS Q1 VCC Vin C R The addition of the RC filter will eliminate instability caused by the leading edge spike on the current waveform. 7(12) Comp/Latch T Figure 24. MOSFET Parasitic Oscillations Figure 25. Bipolar Transistor Drive + – S R 5.0V Ref Q 7(11) 6(10) 5(8) 3(5) RS Q1 VCC Vin Series gate resistor Rg will damp any high frequency parasitic oscillations caused by the MOSFET input capacitance and any series wiring inductance in the gate–source circuit. 6(10) 5(8) 3(5) RS Q1 Vin C1 Base Charge Removal The totem pole output can furnish negative base current for enhanced transistor turn–off, with the addition of capacitor C1.
