Nexperia has extended its constant current LED driver family with eight new AEC-Q101 qualified devices to drive low- and medium-power LEDs up to 250mA. The 16V NCR32xx and 40V NCR42xx series are available in two package styles, the space-saving SOT457 (SC-74) and the SOT223 (SC-73), a slightly-larger option which delivers a higher power capability of up to 1,250mW.

The new LED drivers feature an accurate, stabilised output current of 10mA without an external resistor; if an external resistor is used then the output current is adjustable up to 250mA. Voltage overhead is low at 1.4V. For extra ruggedness, the junction temperature of the drivers is 150°C.

Joachim Stange, Product Manager Bipolar Transistors at Nexperia: “Our growing portfolio of LED drivers addresses the rapidly-expanding market for LEDs in automotive, white goods and consumer applications. Capable of being paralleled, the new NCR32x and NCR42x series are ideally suited to constant current source and automotive applications including interior and exterior lighting such as door handles, dashboards, number plates, indicators and rear lights.”

These new LED drivers are serving Nexperia’s primary market automotive and will increase its already extensive portfolio of AEC-Q101 qualified parts.
