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).

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.
