DC ELECTRICAL CHARACTERISTICS

GND = PGND = 0 V; All voltages with respect to ground; PWM switch rate = 384 kHz; Unless otherwise specified.

Notes:

5.

Normal operation is defined as RSTx/y = HI.

6.

All outputs idle.

7.

Power-Down Mode is defined as RSTx/y = LOW with all input lines held static.

8.

Power supply current increases with increasing PWM switching rates.
