MILPITAS, Calif., June 20, 2022 -- Lumissil Microsystems, a division of Integrated Silicon Solution, Inc. (ISSI),announced today IS32LT3168 LED driver with an integrated Hall Effect Sensor to further expand its portfolioof automotive lighting solutions. The IS32LT3168 is a stand-alone single-channel Linear LED driver in a smallSOP-8 package that can be fully configured via resistors to eliminate the need for a processor and additionalsoftware. It provides a single-channel adjustable constant current source output with PWM dimming controlor automatic Gamma-corrected LED luminosity fading control. It also has an integrated Omni polar Hall-effectsensor that can be used to switch itself or other drivers on/off; making it suitable for all Automotive orIndustrial lighting where a magnet could be used to control LED lights. Example applications includes LEDlighting for vanity mirror, glove compartment, car trunk, car doors puddle light etc. in Autos and forrefrigerator, washer dryer interior lighting activated by door or lid control in White goods & other similarIndustrial applications.

The IS32LT3168 operates over a wide input voltage range (6.5V~28V; 36V maximum) and can withstand 40Vload dump. The device also integrates a low power and high sensitivity unipolar Hall-effect switch to facilitatethe use of a contactless control to the LEDs. The Hall-effect switch operates with either a north or a southmagnetic pole to facilitate different user requirements. For system reliability, it can detect channel outputpin or current setting pin short-to-ground faults and perform thermal shutdown or roll-off shouldtemperature exceed an acceptable threshold to ensure device lifespan. It is AEC-Q100 qualified meeting thestringent automotive quality requirements but can also meet the extended temperature range for theIndustrial market.

The Hall-Effect sensor can be activated in the presence or removal of a magnet. This polarity can beconfigured by floating or grounding an input control pin. The Hall sensor output can be optionally used asinput to enable or disable the driver’s channel output or as control to other drivers or on-board controlcircuits. The IS32LT3168 channel output can be configured for gamma-corrected fading such that the LEDluminosity appears linear to human eyes.

“The IS32LT3168 is our latest addition to the family of automotive-grade LED drivers designed for Automotivelighting applications and the first to integrate magnetic sensors” said Ven Shan, Vice President of Marketing.“This offering adds another dimension to our sensor capability as we extend our current portfolio ofCapacitive Touch and Proximity sensors to include Magnetic sensing thereby expanding the possibilities”. TheIS32LT3168 is a compact,standalone, ultra-low-power, easy to use device. The driver’s single-channel currentsource is adjustable from 20mA to 200mA and only consumes ultra-low standby current of 50μA when the LEDis off. The driver operates over temperature range of -40°C to 125°C and come in a thermally enhanced SOP8-EP package.

Availability and pricingThe IS32LT3168 is priced at $0.71 each per 1K pcs quantities.
