Notes : 1. Versus Pin 4.

2. The output current can reach 4A peak for t

≤ 10µs (up to 120Hz).

3. Provided SOAR is respected (see Figures 1 and 2).

4. Equivalent to discharging a 200pF capacitor through a 0

Ω series resistor.

5. Equivalent to discharging a 150pF capacitor through a 1.5k

Ω series resistor.
