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
2C serial interface adds the flexibility of 6
programmable average battery currents and 4
programmable high voltage output levels for the
flash function.
