General Description

The MAX16824/MAX16825 three-channel LED drivers

operate over a 6.5V to 28V input voltage range. These

devices provide three open-drain constant-current-sink-

ing outputs that are rated to 36V and deliver up to

150mA of current to each string of high-brightness LEDs

(HB LEDs). The current at each output is programmable

by means of an external current-sense resistor. The

MAX16824 features three PWM inputs that control the

duty cycle of the output current, allowing a wide LED

dimming range to be implemented. The PWM inputs

also function as on/off control for each corresponding

output. The MAX16825 offers a 4-wire serial interface, a

3-bit shift register, and a 3-bit transparent latch. The ser-

ial interface allows a microcontroller to configure the out-

put channels using four inputs (DIN, CLK, LE, OE) and a

data output (DOUT). DOUT allows multiple drivers to be

cascaded and operated together.

The MAX16824/MAX16825’s on-board pass elements

minimize the need for external components, while at the

same time, providing ±5% LED current accuracy.

Additional features include a +5V (±5%) regulated output

with 4mA output current capability and thermal protection.

The MAX16824/MAX16825 are available in a thermally

enhanced 16-pin TSSOP-EP package and specified over

the -40°C to +125°C temperature range.
