Table 13. Output Mode Register (Register 0x01)

Bits Bit Name Access 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.
