Function
High Side Current Source Output for Flash LED.
Step-Up DC/DC Converter Output. Connect a 10 µF ceramic capacitor between this pin and GND.
Drain Connection for Internal NMOS and Synchronous PMOS Switches.
Ground
High-Side Current Source Output for Flash LED.
Configurable as a High-Side Current Source Output for Indicator LED or Comparator Input for LED
Temperature Sensing .
Configurable as a Dual-Polarity RF Power Amplifier Synchronization Input, an Interrupt Output, or
as a General Purpose Logic I/O. This pin has an internal 300kΩ pull down to GND.
Active High Hardware Flash Enable. Drive STROBE high to turn on the Flash pulse. This pin has
an internal 300 kΩ pull down to GND.
Input Voltage Connection. Connect IN to the input supply, and bypass to GND with a minimum 10
µF ceramic capacitor.
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 kΩ pull down to GND.
Serial Data Input/Output. High impedance in shutdown or in power down.
Serial Clock Input. High impedance in shutdown or in power down.
Logic High Hardware Enable. HWEN is a high impedance input and is normally connected with
an external pull up resistor to a logic high voltage.
