2. Functionality change
a. The value of the resistor - Rext is changed as below:
For the same IOUT, the Rext of the device version code “B” and “C” is different.
Rext calculation
Device Version Code “B”
Rext = (VR-EXT/ IOUT ) x15.5;
VR-EXT=0.63Volt x G;
Device Version Code “C”
Rext = (VR-EXT/ IOUT ) x23.3;
VR-EXT=0.61Volt x G;
b. Simplify the PWM counting mode and add an enabler of PWM counter reset command
Configuration
register [C:B]
c.
Device Version Code “B”
[C:B]=00: 64X S-PWM
[C:B]=01: 16X S-PWM
[C:B]=10: 4X S-PWM
[C:B]=11: 16- /12-bit PWM
Device Version Code “C”
[C]=0: 64X S-PWM
[C]=1: 16-/12-bit PWM
[B]=0: Disable command of PWM counter reset
[B]=1: Enable command of PWM counter reset
The open-circuit detection code is changed as below:
Device Version Code “B”
1
0
Open circuit
Normal
Device Version Code “C”
0
1
d. Adjust VLED for short-circuit detection
The system may perform the same short detection as device version code “B”. However, the detection
threshold voltage of the device version code “C” is smaller than that of the device version code “B”, the
suitable VLED for short-circuit detection needs to be re-adjusted with a smaller value.
e. Remove parity check and add another method for global latch
Configuration
bit [F]
Device Version Code “B”
Parity bit (even) of configuration
register (Read)
“0”: Correct
“1”: Parity Error
Device Version Code “C”
Data loading (Read / write)
“0”: (Default) 15 times of “data latch” + 1 “global latch”
“1”: 16 times of “data latch” + 1 “global latch”
3. Features Improved
The following table is the comparison between the device version code “B” and “C”:
Item
GCLK
Device Version Code “B” Device Version Code “C”
8 MHz for mode ”00”
30 MHz (VDD=5V)
25MHz for mode ”11”
Latch method
Only "15 data latch + 1
global latch"
Note for Device Version Code“C”
Higher visual refresh rate for
time-multiplexing application
Selectable "15 data latch + 1
global latch" or "16 data latch
+ independent 1 global latch"
PWM counting mode Four modes: 00, 01, 10, 11 Two modes: 00, 11
Mode “11” is not with direct 00 : Scrambled counting
counting
(64X refresh rate)
11 : Direct counting
Error detection
Normal current error
Silent detection (small
detection
current, short time)
PWM counter reset N / A
New command
command
Forced reset for PWM counting if
with multiple clock sources
GCLK reset after
resumed
Keep the driver in OFF state after
GCLK is resumed
Keep the original count
after GCLK is resumed
Reset PWM counter when
GCLK is resumed
Flicker-free detection.
