Table 5-1 Pin Functions
PIN I/O(1) DESCRIPTION
NAME NO.
CL 11 O Adjustable current limit. Connect to device GND if external current limit is not used.
CS 10 O Current-sense output.
DIAG_EN 14 I Enable-disable pin for diagnostics; internal pulldown.
FAULT 9 O Global fault report with open-drain structure, ORed logic for quad-channel fault conditions.
GND 1, 12 — Ground pin.
EN1 3 I Input control for channel 1 activation; internal pulldown.
EN2 4 I Input control for channel 2 activation; internal pulldown.
EN3 5 I Input control for channel 3 activation; internal pulldown.
EN4 6 I Input control for channel 4 activation; internal pulldown.
NC 2, 19, 24 — No connect. This pin is not internally connected. It is recommended to connect this pin to GND to prevent charge buildup; however, this pin can also be left open or tied to any voltage between GND and IN.
SEH 7 I CS channel-selection high bit; internal pulldown.
SEL 8 I CS channel-selection low bit; internal pulldown.
THER 13 I Thermal shutdown behavior control, latch off or auto-retry; internal pulldown.
OUT1 27, 28 O Output of the channel 1 high side-switch, connected to the load.
OUT2 25, 26 O Output of the channel 2 high side-switch, connected to the load.
OUT3 17, 18 O Output of the channel 3 high side-switch, connected to the load.
OUT4 15, 16 O Output of the channel 4 high side-switch, connected to the load.
IN 20, 21, 22, 23 I Power supply.
Thermal pad — — Connect to device GND or leave floating.
