FUNCTIONAL DESCRIPTION
Logic True Table
Power ON/OFF Sequence
SLVS835C – APRIL 2008 – REVISED APRIL 2009............................................................................................................................................................ www.ti.com
The enable/disable of each channel is controlled by logic input signals level at XSLEEP (pin 7 for all channels),
ENAFE (pin 6 for CH4), EN56 (pin 46 for CH5/6) and EN7 (pin 8 for CH7). Table 1 is the summary of the
enable/disable mode.

This device has the power ON/OFF sequence of CH1/2/3/8/REF and CH5/6 for DSC application. The
CH1/2/3/8/REF sequence is shown in Figure 1. The CH5/6 sequence is shown in Figure 2. CH4 and CH7 have
individual sequences but CH4–6 have the subordinate relationship with CH1–3 because the slope of soft start is
the same and puts high priority of CH1–3 to avoid the functional conflict (see the Soft Start description). Due to
this, CH4–6 should not be ON before CH1–3 are ON. When XSLEEP is forced low, all channels turn OFF with
the power OFF sequence.
