LED Drivers for Backlighting

Allegro MicroSystems LED Drivers for Backlighting are a variety of highly integrated LED drivers designed to match requirements for input voltage range, number of LEDs per string, number of strings, and LED current. The LED Drivers offer reliability and robustness, with AEC-Q100 Grade 0 qualification. Furthermore, the LED Drivers for Backlighting feature operation to 150°C, protection against pin-to-pin shorts and open/shorted external components, and built-in fault diagnostic capabilities.

Magnetic Speed Sensor ICs

Allegro MicroSystems Magnetic Speed Sensor ICs offer a comprehensive portfolio covering the full range of speed and speed with direction sensor ICs. These products include a two- and three-wire interface, a magnetic encoder (ring magnet) and gear tooth sensing, Hall and GMR technology, and ASIL-compliant options for transmission, wheel speed, engine, e-motors, and many more encoder and gear tooth sensing applications.

IS32LT3175N/P Single-Channel Linear LED Drivers

ISSI IS32LT3175N/P Single-Channel Linear LED Drivers come with fade in/out and PWM dimming. The regulators serve as a stand-alone LED driver-configurable from 20mA to 150mA with external resistors, no microcontroller is necessary. A logic level “courtesy light” signal from the PWM pin can be interfaced to precisely drive the LED channel. The IS32LT3175P obtains a positive polarity PWM signal. In addition, the IS32LT3175N obtains a negative polarity PWM signal. The regulator integrates a 63-step fade-in and fades out the algorithm (Gamma correction). This causes the output LED current to increasingly rise up to the full source value after the EN pin is pulsed.

LED Drivers

Allegro MicroSystems LED Drivers provide high reliability and robustness in one of the largest selections of wide-input, Grade 0, LED Driver ICs. The devices feature multiple device topologies that cover a wide range of applications.

ALT80800 PWM Dimmable Synchronous Buck LED Driver

Allegro MicroSystems ALT80800 PWM Dimmable Synchronous Buck LED Driver is AEC-Q100 qualified and provides constant current output to drive high-power LEDs. High-side and low-side N-channel DMOS switches are integrated for DC-to-DC step-down conversion, and a true average current is output using a cycle-by-cycle, controlled on-time method. While the output current is user-selectable by an external current sense resistor, the output voltage is automatically adjusted to drive various LEDs in a single string, ensuring optimal efficiency. LED dimming is achieved by a direct logic input pulse-width modulation (PWM) signal at the PWM pin while EN is enabled. However, applying a PWM signal at the EN pin while the PWM pin is high can enable "chopped battery" PWM dimming for legacy control modules. Allegro MicroSystems ALT80800 LED driver is available in a 16-pin TSSOP package with an exposed thermal pad for enhanced thermal dissipation.
