Detailed Description
The MAX16824/MAX16825 are three-channel LED dri-
vers that operate from a 6.5V to 28V input voltage
range. These devices provide three independent open-
drain, constant-current-sinking outputs rated to 36V
and deliver up to 150mA of current to each HB LED
string. The current in each channel is programmable
using an external current-sense resistor in series with
each internal power MOSFET’s source. The MAX16824
features three separate PWM inputs that allow a wide
range of independent dimming level at each of the
three outputs. The PWM inputs also function as on/off
control inputs for each corresponding output (Figure 1).
Maxim Integrated
The MAX16825 includes a 4-wire serial interface to
control the state of each output (Figure 2).
The 4-wire serial interface comprises a 3-bit shift regis-
ter and a 3-bit transparent latch. The shift register is
updated using a clock input (CLK) and a data input
(DIN). DOUT is the last bit of the shift register. This fea-
ture allows multiple drivers to be cascaded and operat-
ed together. The latch is transparent from the shift
register outputs to the LED output when LE is high
while it latches the shift register state on the falling
edge of LE. The output-enable input ( OE) allows simul-
taneous enabling or disabling of all three outputs.
