NAME A1 LED1 Power High-side current source output for flash LED1 A2, B2 OUT Power Step-up DC-DC converter output. Connect a 10-µF ceramic capacitor between this pin and GND. A3, B3 SW Power Drain connection for internal NMOS and synchronous PMOS switches A4, B4 GND Ground Ground B1 LED2 Output High-side current source output for flash LED2 C1 LEDI/NTC Input/Output Configureable as a high-side current source output for indicator LED or comparator input for LED temperature sensing C2 TX1/TORCH/GPIO1 Input/Output Configureable as a dual-polarity RF power amplifier synchronization input, a hardware torch mode enable, or as a general purpose logic I/O. This pin has an internal 300-k Ω pulldown to GND. C3 STROBE Input Active high hardware flash enable. Drive STROBE high to turn on the flash current pulse. This pin has an internal 300-k Ω pulldown to GND. C4 IN Power Input voltage connection. Connect IN to the input supply, and bypass to GND with a minimum 10-µF or larger ceramic capacitor. D1 TX2/INT/GPIO2 Input/Output Configurable as a dual-polarity power amplifier synchronization input, an interrupt output, or as a general purpose logic I/O. This pin has an internal 300-k Ω pulldown to GND. D2 SDA Input/Output Serial data input output. High impedance in shutdown or in power down. D3 SCL Input Serial clock input. High impedance in shutdown or in power down. D4 HWEN Input Logic high hardware enable. HWEN is a high impedance input and is normally connected with an external pullup resistor to a logic high voltage. |
