Phoenix, Ariz. – ON Semiconductor has introduced the CAT3661, a one-channel quad-mode LED driver for low power LED applications such as portable handheld medical equipment.
The CAT3661, which uses a patented architecture and integrates fault protection and diagnostics, is able to drive a single LED backlight with a current of up to 5 mA. Soft-start current limiting and short-circuit protection make the device suitable for use in equipment powered by coin cell batteries. Typical applications include low power backlighting for LCDs and backlighting for a wide range of portable handheld devices including medical equipment.
