2. 8 Load Short Circuit Detection Delay Time (tSHORT)
Load short circuit detection delay time (tSHORT) is a period in which VDO changes to "L" after changing V6 to 1.5 V
instantaneously, after setting S3 to ON from the initial status 1.
2. 9 CTLC Pin Response Time (tCTLC)
CTLC pin response time (tCTLC) is a period in which VCO changes to "L" after changing V7 = VDS instantaneously
from the initial status 1.
2. 10 CTLD Pin Response Time (tCTLD)
CTLD pin response time (tCTLD) is a period in which VDO changes to "L" after changing V8 = VDS instantaneously
from the initial status 1.
3. CCT Pin Internal Resistance, CDT Pin Internal Resistance, CIT Pin Internal Resistance, CCT Pin
Detection Voltage, CDT Pin Detection Voltage, CIT Pin Detection Voltage (Test Circuit 3)
Confirm both VCO and VDO are in "H" after setting V1 = V2 = V3 = V4 = 3.5 V (S-8205A Series), V1 = V2 = V3 = V4 =
V5 = 3.5 V (S-8205B Series), V6 = V9 = V10 = V11 = 0 V (this status is referred to as initial status 2).
3. 1 CCT Pin Internal Resistance (RCCT)
The CCT pin internal resistance (RCCT) can be defined by RCCT = VDS / ICCT by using ICCT when setting V1 = 4.5 V
from the initial status 2.
3. 2 CDT Pin Internal Resistance (RCDT)
The CDT pin internal resistance (RCDT) can be defined by RCDT = VDS / ICDT by using ICDT when setting V1 = 1.5 V
from the initial status 2.
3. 3 CIT Pin Internal Resistance (RCIT)
The CIT pin internal resistance (RCIT) can be defined by RCIT = VDS / ICIT by using ICIT when setting V6 = VDIOV +
0.015 V from the initial status 2.
3. 4 CCT Pin Detection Voltage (VCCT)
The CCT pin detection voltage (VCCT) is V9 when VCO is set to "L" after increasing V9 gradually, after setting V1 =
4.5 V from the initial status 2.
3. 5 CDT Pin Detection Voltage (VCDT)
The CDT pin detection voltage (VCDT) is V10 when VDO is set to "L" after increasing V10 gradually, after setting V1
= 1.5 V from the initial status 2.
3. 6 CIT Pin Detection Voltage (VCIT)
The CIT pin detection voltage (VCIT) is V11 when VDO is set to "L" after increasing V11 gradually, after setting V6 =
VDIOV + 0.015 V from the initial status 2.
