Overview
The FAN5702UC15X is a charge pump LED driver IC manufactured by onsemi, designed for mobile handset applications. It features six configurable output channels with an adjustable output voltage and a maximum output current of 30 mA per channel. The device operates within a supply voltage range of 2.7 V to 5.5 V and utilizes an internal switching frequency of 1.2 MHz. Control is managed via I2C interface supporting PWM dimming. It is housed in a compact 16-WLCSP package measuring 1.71x1.71 mm and functions reliably across a temperature range of -40°C to +85°C.
Feature Summary
- Integrates a charge pump topology to drive multiple LEDs from low-voltage sources
- Supports digital control through I2C interface for configuration and PWM dimming
- Features six independent output channels with adjustable current settings
Applications
- Mobile handset backlighting
- Portable media player displays
- LCD backlight systems
Procurement Notes
Verify component status as the FAN5702UC15X is listed as obsolete or end-of-life by the manufacturer. Confirm availability through authorized distributors or secondary market suppliers like Rochester Electronics. Ensure compliance with RoHS3 specifications and check for relevant Product Change Notifications regarding packaging or assembly updates before procurement.
Selection Notes
Select this component for space-constrained portable devices requiring multi-channel LED driving. The WLCSP package minimizes board area. Verify that the required LED forward voltage falls within the charge pump capabilities and that the system power budget accommodates the 30 mA per channel limit. Ensure I2C bus compatibility with the host processor.
Part Context
This part belongs to the FAN5702 series of LED drivers from onsemi. It shares architectural similarities with other members like the FAN5701 but differs in output current ratings and specific application tuning. The UC15X suffix denotes the specific package type and tape/reel configuration suitable for automated surface-mount assembly processes.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. As the component is obsolete, engineering teams should evaluate alternative LED drivers from the same family or newer generations that offer compatible pinouts and electrical characteristics.
