Pin Function Descriptions Pin No. WLCSP LFCSP Mnemonic Description A1 N/A1 PGND Power Ground. A2 N/A1 SGND Signal Ground. A3 1 VIN Input Voltage for the Device. Connect an input bypass capacitor close to this pin. B1 8 SW Boost Switch. Connect the power inductor between SW and the input capacitor. B2 2 GPIO2 ILED/TX2/ADC. Mode is register selectable. Red indicator LED current source or TxMASK2 or ADC input. ILED Mode. Connect to red LED anode. Connect the LED cathode to power ground. TxMASK2 Mode. Reduces the current to the programmable TxMASK2 current. ADC Mode. This pin is used as the input pin for the ADC. B3 3 GPIO1 Torch/TX1. Mode is register selectable. External torch mode or TxMASK1 input. Torch Mode. Enables the integrated circuit (IC) in direct torch mode. TxMASK1 Mode. Reduces the flash current to the programmable TxMASK1 current. C1 7 VOUT Boost Output. Connect an output bypass capacitor very close to this pin. This is the output for the 5 V external voltage mode. C2 10 STROBE Strobe Signal Input. This pin synchronizes the flash pulse to the image capture. In most cases, this signal comes directly from the image sensor. C3 9 EN Enable. Set EN low to bring the quiescent current (IQ) to <1 μA. Registers are set to their defaults when EN is brought from low to high. D1 6 LED_OUT LED Current Source. Connect this pin to the anode of the flash LED. D2 4 SDA I2C Data Signal in I2C Mode. D3 5 SCL I2C Clock Signal in I2C Mode. 0 EPAD Exposed Pad. Connect the exposed pad to the ground plane for the LFCSP version. 1 N/A means not applicable. |
