FIGURE 9. ALS Control / Silicon Revision Register
Description
Internal Hex Address: 0x50
•
Rev0-Rev1 : Stores the Silicon Revision value. LM3535 =
'11', LM3535-2ALS = '00'
•
AVE2-AVE0: Sets Averaging Time for ALS sampling.
Need two to three Averaging periods to make transition
decision.‘000’ = 25ms, ‘001’ = 50ms, ‘010’ = 100ms, ‘011’
= 200ms, ‘100’ = 400ms, ‘101’ = 800ms, ‘110’ = 1.6s, ‘111’
= 3.2s

ALS Resistor Control Register Description
Internal Hex Address: 0x51
FIGURE 10.
•
R3A-R0A are valid on both the LM3535 and
LM3535-2ALS.
•
R3B-R0B are only valid on LM3535-2ALS.
•
R0-R3: Sets the internal ALS resistor value

•
CP-EN: Forces the LM3535 to operate in the gain of 1.5x
exclusively when the Dx current sinks are enabled.

SEL1-SEL0: ALS Selection Bits. SEL1 and SEL0
determine how the ALS sensor information is processed.
'00' = Min. of ALSA and ALSB used, '01' = ALSA used and
ALSB ignored (DEFAULT), '10' = ALSB Used and ALSA
ignored, '11' = Max. of ALSA and ALSB used.

FIGURE 12. Zone Boundary Register Descriptions
•
ZB7-ZB0: Sets Zone Boundary Lines with a Falling ALS
voltage.
0xFF w/ ALS Falling = 992.3mV (typ.).
V
TRIP-LOW (typ) = [Boundary Code × 3.874mV] + 4.45mV
For boundary codes 2 to 255. Code 0 and Code1 are
mapped to equal the Code2 value.
Each zone line has approx. 5.5mV of hysteresis between
the falling and rising ALS trip points..
•
Zone Boundary 0 is the line between ALS Zone 0 and Zone
1. Default Code = 0x33 or approx. 200mV
•
Zone Boundary 1 is the line between ALS Zone 1 and Zone
2. Default Code = 0x66 or approx. 400mV
•
Zone Boundary 2 is the line between ALS Zone 2 and Zone
3. Default Code = 0x99 or approx. 600mV
•
Zone Boundary 3 is the line between ALS Zone 3 and Zone
4. Default Code = 0xCC or approx. 800mV
