Figure 17 External Component Diagram

In an application where ENABLE is fed directly from VDD rather than a dedicated control line,

resistor R3 and capacitor C9 are used on the ENABLE pin to introduce a short delay in the Low to

High transition of ENABLE. This will ensure the pin goes high after power supplies have had time

to settle (see “ENABLE Operation” in the “Hardware Control Modes” section of the datasheet).

However, if the ENABLE signal is being provided from an external controller chip rather than VDD

directly, R3 and C9 will not be required.
