FIGURE 1. 1-WIRE XSD INTERFACE
The ISL97632 uses a simple single-wire serial interface for
programming the output brightness of the LEDs. A 5-bit
interface is used to give a total of 32 levels of output
brightness. The interface uses a normally high connection
for use with open-drain driving schemes and Intersil’s
proprietary 1-Wire XSD bus. When held low for between
15μs and 45μs, the interface registers a logic 1. When held
low for between 90μs and 120μs the interface registers a
logic 0. When held low for greater that 215μs, the interface
loads the last 5 bits into the brightness control register and
updates the brightness level. The required minimum high
time is 3μs. This simple single-wire programming is
summarized as follows:
? Logic 0 = Negative pulse >90μs and <120μs
? Logic 1 = Negative pulse >15μs and <45μs
? Load = Negative pulse >215μs
Figure 1 shows an example of programming a binary code of
10100 and load it in to the device serial register.
The serial interface is automatically reset to 0 when the
device is disabled, or enters UVLO. Therefore, when the part
is enabled, the output brightness is automatically set to the
minimum level.
