Three channel, high pressure, high brightness LED linear actuator

MAX16824/MAX16825 is a 3 channel, LED driver, in 6.5V to 28V input voltage range. These two devices provide three way open drain, fixed suction current output for each string of high brightness LED (HB LED) provide ratings for the current 36V, up to 150mA. Each output current can be set by an external current resistor. MAX16824 has three PWM input, used to control the duty cycle of the output current can be achieved in a wide range of dimming LED. PWM input can also be on / off control for each output. MAX16825 provides 4 - wire serial port, the 3 - bit shift register and the 3 - bit transparent latch. The serial port allows the microcontroller to configure the output channel through four inputs (DIN, CLK, LE, and active low level OE) and a data output (DOUT). MAX16824/MAX16825 built-in adjustment tube to minimize the number of external components, and provide + 5% LED output current accuracy. The device also includes providing 4mA output current of +5V (+ 5%) voltage output and thermal protection function. MAX16824/MAX16825 uses an enhanced heat dissipation 16 pin TSSOP-EP package that operates from -40 C to +125 DEG C temperature range. The key characteristics of application / use 6.5V to 28V working voltage range for LED series high voltage, can be connected to the 36V output power three rated 36V output channels can be adjusted independently of LED current per channel output current up to 150mA + 5% LED current PWM dimming accuracy 3 independent dimming control input (MAX16824) through 4 wire serial port on the LED current chopping control (MAX16825) (+5V + 5%) regulator output, 4mA current source rapid response to adjust the brightness of 200mV flow detection benchmark helps to reduce the power consumption thermal shutdown -40 DEG to +125 DEG C C temperature range enhanced heat dissipation, with 16 pin TSSOP package bare pad
