BD83732HFP-M
General Description
BD83732HFP-M and BD83733HFP-M are 50V tolerant
LED current drivers. Suitable for Automotive LED
applications, it can control light through constant current
output with control using PWM.
Having LED open/short detective circuit and LED current
de-rating functions integrated, it can deliver high reliability.
By utilizing Rohm’s patented PBUS function, it is possible
to turn OFF all LEDs when a row of LEDs are
short/open-circuited if multiple number of the ICs are used
In case the LED connected to the output IOUT terminal
has 2 LEDs in serise, BD83732HFP-M has to be used, in
case of 3 LEDs in series - BD83733HFP-M ( Refer to
Page.18 LED Open Detection / Disable LED Open
Detection ).
BD83733HFP-M

Problems with implementing YUV2RGB in arm assembly
The following formula is needed for YUV2RGB: R = Y + 1.402 (Cr - 128) G = Y - 0.34414 (Cb - 128) - 0.71414 (Cr - 128) B = Y + 1.772 (Cb - 128) To avoid floating-point operations, change to R = Y + (91...
