Is Now Part of To learn more about ON Semiconductor, please visit our website at www.onsemi.com Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor product management systems do not have the ability to manage part nomenclature that utilizes an underscore (_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated device numbers.

FAN5701 — Compact 6-LED Driver for Mobile Platforms Features Description    Six (6) Parallel LEDs (up to 30mA each) The FAN5701 is a highly integrated and efficient chargepump-based multi-LED driver. The device can drive up to six LEDs in parallel with a total output current of 180mA.    >600:1 Dimming Ratio for 100Hz PWM Frequency     Wide Input Range: 2.7V to 5.5V   Total Package Load Current Capability: 180mA Two Default Groups of Four (4) and Two (2) LEDs for Main and Sub-Display Lighting with Individual PWM Dimming Controls that Operate up to 20kHz Up to 92% Efficiency Built-in 1.5x Charge Pump with Low-Dropout Bypass Switch Over-Temperature Protection 1.2MHz Switching Frequency for Small-Sized Capacitors 16-Bump 1.61mm x 1.61mm WLCSP (0.6mm Height) The FAN5701 can be ordered with ISET values of 30mA, 20mA, 15mA, or 8mA and available in WLCSP or ultra-thin UMLP package types. The default ISET is always determined by the part number purchased (see Ordering Information) . Applications     Regulated internal current sinks deliver excellent current and brightness matching to all six LEDs. The device provides excellent efficiency without an inductor by operating the charge pump in 1.5x or pass-through modes. VOUT Over-Voltage and Short-Circuit Protection 16-Lead 3.0mm x 3.0mm UMLP (0.55mm Height) The FAN5701 is capable of driving a primary display backlight requiring four to six LEDs. When more than four LEDs are needed for backlighting, the FAN5701’s two PWM dimming inputs can be connected together to provide the proper dimming control for all six LEDs. When a primary and sub-display is needed, the FAN5701 can be controlled such that each group can be dimmed independently. For candybar phones requiring a primary display and keypad lighting, the FAN5701 offers a simple, and compact lighting solution.

The maximum total output current for the IC should be limited to 180mA. The total output current can be split between the two groups (IDxA = IDxB = 30mA maximum). Under maximum output current conditions, special attention must be given to input voltage and LED forward voltage to ensure proper current regulation. See the Maximum Output Current section of the datasheet for more information. 4. For the two groups of current sinks on a part (GroupA and GroupB), the following are determined: the maximum sink current in the group (MAX), the minimum sink current in the group (MIN), and the average sink current of the group (AVG). For each group, two matching numbers are calculated: (MAX-AVG)/ AVG and (AVG-MIN)/AVG. The largest number of the two (worst case) is considered the matching figure for the group. The matching figure for a given part is considered to be the highest matching figure of the two groups. The typical specification provided is the most likely norm of the matching figure for all parts. 5. For each Dxx pin, headroom voltage is the voltage across the internal current sink connected to that pin. VHRx = VOUT VLED. If headroom voltage requirement is not met, LED current regulation is compromised. © 2009 Fairchild Semiconductor Corporation FAN5701 • Rev. 1.0.3 www.fairchildsemi.com 6 FAN5701 — Compact 6-LED Driver for Mobile Platforms Electrical Specifications VIN = 3.6V, TA = 25C, ILED = 20mA, and LED cathode terminals = 0.4V.

The tightly matched current sinks ensure uniform brightness across the LEDs. Each LED is configured in a common anode configuration with its peak drive current set during manufacturing (see Ordering Information and ISET). Charge Pump The charge pump operates in either 1x mode, where VOUT is connected to VIN through a bypass switch, or in 1.5x mode. The circuit operates in 1x mode until the LED with the highest forward voltage (VLED(MAX) ) can no longer maintain current regulation. At that point, 1.5x mode begins. If the lowest active cathode voltage is greater than 1.8V, the charge pump switches back to 1x mode. In addition to hysteresis, a 1ms transition delay is provided for the device to ignore short-duration input voltage drops in deciding mode transitions. IC Enable When the EN pin is LOW, all circuit functions are disabled. When the EN pin HIGH, the entire chip is enabled. Both PWM inputs are now functional. © 2009 Fairchild Semiconductor Corporation FAN5701 • Rev. 1.0.3 PWM Dimming External PWM inputs (group A and group B) directly modulate output currents in their corresponding LED channels to vary the perceived LED brightness. Two PWM inputs are provided to control two independent groups of LEDs, such as that of a main display panel and a secondary panel. They can also be connected to a single input to simultaneously dim all six LED outputs. VOUT Short-Circuit Protection The FAN5701 has integrated protection circuitry to prevent the device from being short circuited when the output voltage falls below 2V. If this occurs FAN5701 turns off the charge pump and the LED driver outputs, but a small bypass switch is left on. The device monitors the output voltage to determine if it is still in short circuit condition and, once it has passed, FAN5701 soft-starts and returns to normal operation. VOUT Over-Voltage Protection If the output voltage goes above 6V, the FAN5701 shuts down until this condition has passed. The charge pump and LED driver outputs are turned off. Once this condition has passed, FAN5701 soft-starts into normal operation. www.fairchildsemi.com 9 FAN5701 — Compact 6-LED Driver for Mobile Platforms Circuit Description FAN5701 — Compact 6-LED Driver for Mobile Platforms Physical Dimensions 0.03 C E 2X F A B 0.40 A1 BALL A1 INDEX AREA (Ø0.20) Cu Pad D 0.40 (Ø0.30) Solder Mask Opening 0.03 C 2X RECOMMENDED LAND PATTERN (NSMD PAD TYPE) TOP VIEW 0.06 C 0.625 0.547 0.05 C C SEATING PLANE 0.378±0.018 0.208±0.021 E D SIDE VIEWS NOTES: A.
