LED Drivers with LED Current Foldback
Binning Adjustment Register (0x00)
The Binning Adjustment register is a 4-bit register that
sets the differential regulation voltage reference
between CS+ and CS-. Only the first 4 bits of the data
byte update the Binning Adjustment register. The
remaining 4 bits are ignored. See Table 3. The factory-
default register value is 198mV.
Ramp Peak Register (0x01), MAX16806
The Ramp Peak register is a 3-bit register that sets the
maximum peak value of an internally 200Hz generated
ramp. The ramp signal can be programmed for a peak
value of 1.55V to 2.88V. Only the first 3 bits of the data
byte update the Ramp Peak register. The remaining 5
bits are ignored (see Table 4). The factory-default reg-
ister value is 2.88V.
Table 3. Binning Adjustment
LED Current Foldback Threshold
(LED_CFT) Register (0x02)
LED_CFT is a 4-bit register that sets the threshold for
the onset of the LED current foldback operation. Only
the first 3 bits of the data byte program the LED_CFT
register. Bit 3, not shown in Table 5, sets the LED cur-
rent foldback range.
The MAX16805/MAX16806 start dimming the LED cur-
rent when the input voltage exceeds the LED current
foldback threshold. For bit 3 = 0, the dimming range is
1.2 times the programmed ramp peak voltage. For bit 3
= 1, the dimming range is 2.4 times the programmed
ramp peak. To disable the LED current foldback feature
of the MAX16805/MAX16806 connect CFT to GND. The
factory-default register value is 16V.
