00h
IPWM1 Current setting
IPWM (9001)

01h
IPWM2 Current setting
(Not used for 9001)
8
02h
IPWM3 Current setting
(Not used for 9001)
8
User Loads code 08h ( 8 decimal) for 1 mA peak current
For PWM control current output.
This is only valid user code.
03h
IPWMx and TSENSEx
Channel Enable

User loads 2Ah for 9003.
User loads 02h for 9001.
04h
Global PWM Dimming
8
Log mode: (default)
Simultaneously decreases PWM duty cycle for IPWMx
Data Code 00h = 0 dB dimming, FEh = – 72 dB FFh = OFF
Example: 50% brightness reduction ( – 6dB) requires:
– 6dB / – 0.17dB = 35 (decimal) = 23h steps
Linear Mode:
Simultaneously decreases ILED in banks A – C by subtracting
Global Dimming Code (Reg04h data) from PWM Duty Cycle
Code (Reg05h – Reg07h data)
Data Code 00h = 0 dimming, If Global Dimming Code is
equal or exceeds PWM Duty Cycle Code, ILED = 0 mA.
05h
IPWM1 User Duty Cycle
IPWM (9001)
8
Log Mode:
~ – 0.17dB dimming per LSB for currents > 300 A; Refer to
8 to 12 bit conversion curve (Figure 3 and Table 10) for
resolution in range 0 – 300 A
Data Code 00h = 0% Duty Cycle, FFh = 100% Duty Cycle
Example: 50% brightness reduction ( – 6dB) requires: 255 –
(– 6 dB / – 0.17 dB) = 255 – 35 = 220 (decimal) = DCh steps
06h
IPWM2 User Duty Cycle
IPWM (9001)
8
Same as above for reg 05h
07h
IPWM3 User Duty Cycle
IPWM (9001)
8
Same as above for reg 05h
19h
LED Diagnostics Test
8
See Table 2; Bit 5 = 1 sets user-initiated LED short/open
diagnostic
1Ch
LED Faults Status
( shorted to GND)
5
Bits from bit 5 to bit 0 represent LED status for sensed LEDs
Bit =1 LED short to GND
1Dh
LED Faults Status
(shorted to VIN/open)
5
Bits from bit 5 to bit 0 represent LED status for sensed LEDs
respectively. Bit = 1 represents LED shorted to VIN/open
1Eh
Configuration register
8
See Table 3
1Fh
Software reset, Standby
8
See Table 4
49h
Ta-Tj Temperature Offset
8
Since LED junction temperature is measured, the values
loaded here allow an offset to account for Tj – Ta gradient.
This allows correction tables to be referenced to ~ Ta levels.
Two 4 bit offsets value for the LED and the Si Diode;
Bit [7:4] = Tj-Ta offset for the LEDs
