MAX16835ATE+

The MAX16835ATE+ is a high-voltage, 350mA, adjustable linear high-brightness LED driver in 16 pin TQFN package. The current regulator operates from a 6.5V to 40V input voltage range and delivers up to a total of 350mA to one or more strings of high-brightness LEDs (HB LEDs). The output current of the MAX16835 is adjusted by using an external current-sense resistor in series with the LEDs. An enable input allows wide range "pulsed" dimming. Wave-shaping circuitry reduces EMI. The differential current-sense input increases noise immunity. The MAX16835 is well suited for applications requiring high-voltage input and is able to withstand automotive load-dump events up to 40V. An on-board pass element minimizes external components while providing ±3.5% output current accuracy. It is used in automotive interior, automotive exterior, warning lights, navigation and marine indicators, general illumination, signage, gasoline canopies and beacons.

• Adjustable LED current (35mA to 350mA)
• ±3.5% output current accuracy
• Integrated pass element with low-dropout voltage (0.55V typ)
• Output short circuit protection, thermal shutdown
• 5V regulated output with 4mA source capability
• Differential LED current sense
• High voltage enable pin for dimming interface
• Low shutdown supply current (35μA typ), operating temperature range from -40°C to +125°C
• Low 200mV current-sense reference reduces power losses
• Wave-shaped edges reduce radiated EMI during PWM dimming
