General Description
The MX881 offers a highly integrated Xenon Flash controller,
providing an ideal solution for small form factor flash and torch
lighting applications. The MX881 integrates a user
programmable Controller, IGBT Driver, 100mA LED Torch
Driver, and Transformer Drive Transistor to significantly reduce
component count, solution size, and design complexity.
The Boost Control Logic manages the peak primary current and
off time to optimize charge time and control average battery
current.
The Charge Cycle Control starts the charge cycle on a low to
high transition of the CHARGE input. Then detects when the
output voltage has reached the desired voltage and stops the
Boost Control Logic, while asserting the DONE output signal.
The SPI/I
average battery currents and 4 programmable high voltage
output levels for the flash function.
