Notes:

1.

See "8.Ordering Guide" on page 23 for more information.

2.

Minimum value of (VDD - GND) decoupling capacitor is 1 µF.

3.

Both VO pins are required to be shorted together for 4.0 A compliance.

4.

When performing this test, it is recommended that the DUT be soldered down to the PCB to reduce parasitic

inductances, which may cause over-stress conditions due to excessive ringing.

5.

Guaranteed by characterization.
