MILPITAS, Calif., June 20, 2022 (GLOBE NEWSWIRE) — 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 portfolio of automotive lighting solutions. The IS32LT3168 is a stand-alone single-channel Linear LED driver in a small SOP-8 package that can be fully configured via resistors to eliminate the need for a processor and additional software. It provides a single-channel adjustable constant current source output with PWM dimming control or automatic Gamma-corrected LED luminosity fading control. It also has an integrated Omni polar Hall-effect sensor that can be used to switch itself or other drivers on/off, making it suitable for all Automotive or Industrial lighting where a magnet could be used to control LED lights. Example applications includes LED lighting for vanity mirror, glove compartment, car trunk, car doors puddle light etc. in Autos and for refrigerator, washer dryer interior lighting activated by door or lid control in White goods & other similar Industrial applications.

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