Programmable Switch-Mode LED Driver
with Analog-Controlled PWM Dimming
FAULT 1-Wire Interface
The MAX16816 features a FAULT output multiplexed
with a 1-Wire programming interface. Once the voltage
at UVEN exceeds the UVLO threshold, the device is
enabled and FAULT will pulse low once, indicating the
beginning of the programming window. Two program-
ming mode entry codes must be entered within 8ms
after the pulse to enter programming mode (see Table
1). The MAX16816 will register the second entry code
only after the first code has been received. Once the
MAX16816 successfully enters programming mode, the
data and clock for the 1-Wire interface are supplied
through FAULT .
Once the programming window has passed, the EEPROM
is no longer accessible without cycling power to the
Table 1. Programming Mode Entry Codes
device. Under these conditions, FAULT will go low only
when a fault (overvoltage, overcurrent, or HICCUP mode)
occurs or when the supply voltage drops below the UVLO
threshold.
EEPROM and Programming
Nonvolatile EEPROM is available to configure the
MAX16816 through a 1-Wire serial interface. Registers
are located in a linear address space as shown in
Table 2. All other EEPROM locations are reserved.
Configure the six control registers to adjust parameters
including the REG2 voltage, soft-start durations, blank-
ing time, LED load current (binning), slope compensa-
tion, and to enable/disable the RTOF oscillator. See the
1-Wire Interface section for more information about
1-Wire programming.
