Figure 3. Block Diagram

Table 1. Absolute Maximum Ratings

Note: 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 6 and 7).

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

Ω series resistor.

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

Ω series resistor.
