STMicroelectronics’ L99LDLH32 linear present regulator delivers a handy, built-in answer for dynamic automotive lighting managed utilizing CAN-FD Mild protocol. Superb to be used with OLED lamps that present vibrant, homogeneous, and high-contrast lighting from a small floor space, the brand new driver lets designers produce advanced gentle patterns and results that improve security and styling.
Monolithically built-in utilizing ST’s BCD9sL course of, the L99LDLH32 is AEC-Q100 certified. It’s out there as 7mm x 7mm QFN48 package deal with wettable flanks and an uncovered thermal pad to help dissipation. With 32 regulated present sources, independently programmable from 1mA to 15mA, the L99LDLH32 can drive particular person pixels in exterior and inside lighting functions. World dimming can also be supplied, with 8-bit decision. Whereas powered on the car battery voltage, the driving force produces outputs of as much as 35V to cowl a large gentle emitter forward-voltage unfold. The built-in CAN FD Mild protocol handler and transceiver simplify connection to the car’s communication infrastructure and controlling area ECU (digital management unit). Primarily based on confirmed business requirements, CAN FD Mild’s synchronized commander/responder communication, conceived for controlling easy units like lights and sensors, saves pricey exterior parts comparable to timing crystals.
Then again, the info bandwidth of 1Mbit/s allows designers to create advanced animated gentle patterns and permits easily modulated transitions and dimming. As well as, on-chip non-volatile reminiscence permits programming of parameters comparable to present stage and PWM dimming for stand-alone operation, to offer a failsafe mode to cowl malfunctioning of the communication bus or controller. Concentrating on roles together with safety-critical lighting comparable to taillights, stoplights, and switch indicators, the L99LDLH32 supplies options for a excessive stage of purposeful security. These embody a fault-status pin, voltage and temperature displays, a programmable timeout watchdog, and short-circuit and open-load detection. As well as, frequency dithering optimizes and minimizes electromagnetic emissions.
