Description

[7:6]

IL_PEAK

R/W

These bits set the inductor peak current limit.

00 = 2.25 A.

01 = 2.75 A.

10 = 3.25 A (default).

11 = 3.5 A.

5

STR_LV

R/W

This bit sets the sensitivity for the STROBE pin.

0 = edge sensitive.

1 = level sensitive (default).

4

STR_MOD

R/W

This bit sets the strobe mode.

0 = software strobe mode; software flash occurs when the output is enabled in flash mode.

1 = hardware strobe mode; the STROBE pin must go high for flash (default).

3

STR_POL

R/W

This bit sets the polarity of the STROBE pin.

0 = active low.

1 = active high (default).

[2:0]

LED_MOD

R/W

These bits set the LED output mode.

000 = standby mode (default).

001 = fixed 5 V output mode.

010 = assist light mode.

011 = flash mode.

100 = independent trigger mode with timeout enabled.

101 = independent trigger mode with timeout disabled.

110 = fixed 5 V output mode with torch mode (total output current must be below 500 mA).

111 = reserved.
