Thông Tin Sản Phẩm
Tổng Quan Sản Phẩm
The MAX16823ATE+ is a high voltage, 3-channel linear high brightness LED driver with open LED detection in 16 pin TQFN package. This LED driver operates from a 5.5V to 40V input voltage range and delivers up to 100mA per channel to one or more strings of high brightness LEDs (HB LEDs). Each channel's current is programmable using an external current sense resistor in series with the LEDs. Three DIM inputs allow a wide range of independent pulsed dimming in addition to providing the on and off control of the outputs. It is well suited for automotive applications requiring a high voltage input and is able to withstand load-dump events up to 45V. Additional features include an active-high, open-drain LEDGOOD output for open LED detection, a +3.4V (±5%) regulated output with 4mA output current capability. It is used in emergency vehicle warning lights, navigation and marine indicators, architectural and industrial lighting.
- Adjustable constant output current (5mA to 100mA and up to 2A with external BJT)
- On-board pass elements minimize external components while providing ±5% LED current accuracy
- Output short-circuit and thermal protections, operating temperature range from -40°C to 125°C
- Open LED detection, under voltage lockout, 1.5mA ground current at IOUT1 = IOUT2 = IOUT3 = 70mA
- Three independent high voltage DIM inputs, 3.4V voltage regulator with 4mA capability
- Three integrated pass elements with low dropout voltage (0.7V max)
- Wave shaping circuitry reduces EMI while providing fast turn-on and turn-off times
- Accurate, low 203mV current sense
- Overtemperature shutdown
- Output current slew rate of 8mA/µs
