Oscillator Off
VCC > 12.1V(VCCUV+)
T J <135oC (Tjmax)
Oscillator On
UVLO Mode
1/2 -Bridge Off
IQCC ≅ 300 μA
Oscillator Off
CSD = 0V
VCC < 5.5V (VCCUVL-)
(Power Turned Off)
FAULT Mode
VCC > 12.1V (VCCUV+)
T J <135oC (Tjmax)
Oscillator On
1/2 -Bridge Off
Oscillator Off
VCC < 10.5V (VCCUV- )
(Phase Cut Dimming)
VCC < 10.5V (VCCUV- )
(Phase Cut Dimming)
Auto-Restart Timeout
(VCSD < 2.4V) (VCSDRS)
CSD switched to run mode
SOFTSTART
Mode
1/2 - Bridge On
Initial frequency 130kHz
CSD charged from Isource
Frequency ramps down to
f(min)
Fault Detected
(Vpk at VCS > 0.56V)(VCSOL )
T J <135oC (Tjmax)
(Over-Temperature)
VCSD > 5.2V
(End of SOFTSTART Mode)
CSD switched to Comp function
RUN Mode
Voltage compensation active
CSD varies between
VCSD (min) = 0 for f(min)
to VCSD(max) = 5.5V for f(max)
Fault Detected
(Vpk at VCS > 9V)
(VCSLATCH)
T J <135oC (Tjmax)
(Over-Temperature)
CSD switched to
run mode
Fault Detected (Vpk at VCS > 0.56V (VCSOL ))
CSD switched to Shutdown Circuit
CSD discharged to 0V
Frequency defaults to f(min)
SHUTDOWN Mode
1/2 -Bridge Off
CSD is slowly discharged
Fault Confirmed
(VCSD > 12V)
(VCSDSD)
Fault Timing Mode
1/2 - Bridge On
CSD initialized to 5V (VCSDOL)
VCS >0.56V(VCSOL)=Overload:CSD slow charge
VCS > 1.2V (VCSSC) = Short Circuit : CSD
Fault Removed
(Vpk at VCS < 0.5V)
(VCSOL)
Delay
CSD is slowly
discharged to 2.4V
fast charge
(VCSDRS)
All values are typical
NOTE: If the IR2161 die temperature exceeds 135o at any time the system will enter FAULT Mode. At a typical frequency of
40kHz, the die temperature is approximately 12oC above the ambient air temperature
