5 / 16 page ADM8843 Rev. 0 | Page 5 of 16 PIN CONFIGURATION AND FUNCTION DESCRIPTIONS PIN 1 INDICATOR 1 VOUT 2 C2+ 3 ISET 4 GND 11 C2– 12 CTRL2 10 GND 9 GND TOP VIEW (Not to Scale) ADM8843 Figure 2. Pin Configuration Table 3. Pin Function Descriptions Pin No. Mnemonic Description 1 VOUT Charge Pump Output. A 2.2 µF capacitor to ground is required on this pin. Connect VOUT to the anodes of all the LEDs. 2 C2+ Flying Capacitor 2 Positive Connection. 3 ISET Bias Current Set Input. The current flowing through the RSET resistor, ISET, is gained up by 120 to give the ILED current. Connect a resistor RSET to GND to set the bias current as VSET/RSET. Note that VSET = 1.18 V. 4, 9, 10 GND Device Ground Pins. 5–8 FB1–FB4 LED1–LED4 Cathode Connection and Charge Pump Feedback. The current flowing in these LEDs is 120 times the current flowing through RSET, ISET. When using fewer than four LEDs, this pin can be left unconnected or connected to GND. 11 C2− Flying Capacitor 2 Negative Connection. 12 CTRL2 Digital Input. 3 V CMOS Logic. Used with CTRL1 to control the shutdown operation of the main and sub LEDs. 13 CTRL1 Digital Input. 3 V CMOS Logic. Used with CTRL2 to control the shutdown operation of the main and sub LEDs. 14 C1− Flying Capacitor 1 Negative Connection. 15 VCC Positive Supply Voltage Input. Connect this pin to a 2.6 V to 5.5 V supply with a 4.7 µF decoupling capacitor. 16 C1+ Flying Capacitor 1 Positive Connection. - EP Expose Paddle. Connect the exposed paddle to GND. |
