The new MAX16831 from Maxim is a high-voltage, high-power, constant-current LED driver with analog and PWM dimming.
It integrates a floating LED current-sense amplifier and dimming MOSFET driver to minimise component count and ensure high reliability in automotive and general lighting applications that utilise high-brightness LEDs. Designed to withstand harsh operating environments, the device operates from a 5,4 V to 76 V input-voltage range, thus ensuring cold-start and load-dump (up to 80 V) compliance. Specifically tailored to meet the requirements of the latest front-light automotive designs, it is ideal for high- and low-beam assemblies, adaptive front-light systems, daytime-running lights (DRLs), and fog lamps.
The device features high-efficiency operation and a wide (1000:1) dimming range with analog or PWM control. The analog control signal is compared to an on-board 200 Hz ramp and can be used to simplify designs that require multilevel brightness adjustment. Providing plusmn;5% accurate LED-current control over the entire automotive operating-temperature range, this LED driver ensures excellent brightness matching. A very low 100 mV LED current-sense reference and an internal gate driver with 1,4 A/2 A source/sink capability allow for high efficiency and, therefore, minimal heat dissipation. A dedicated enable/shutdown input ensures that the shutdown-mode current remains below 45 μA.
Other features are output over-voltage and over-current protection, as well as over-temperature and LED short-circuit protection. Fully specified for the -40°C to +125°C automotive temperature range, it is available in a lead-free, 5 mm x 5 mm, 32-pin TQFN package with exposed pad.
