2. 6 CTLC Input Voltage “H” (VCTLCH), CTLC Input Voltage “L” (VCTLCL)
The CTLC input voltage “L” (VCTLCL) is the CTLC pin’s voltage; when the COP pin’s voltage is set to “L” after
decreasing the CTLC pin’s voltage gradually from the initial status. After that, increasing the CTLC pin’s voltage
gradually, the CTLC pin’s voltage when the COP pin’s voltage is set to “H”; is the CTLC input voltage “H” (VCTLCH).
2. 7 CTLD Input Voltage “H” (VCTLDH), CTLD Input Voltage “L” (VCTLDL)
The CTLD input voltage “L” (VCTLDL) is the CTLD pin’s voltage; when the DOP pin’s voltage is set to “L” after
decreasing the CTLD pin’s voltage gradually from the initial status. After that, increasing the CTLD pin’s voltage
gradually, the CTLD pin’s voltage when the DOP pin’s voltage is set to “H”; is the CTLD input voltage “H” (VCTLDH).
2. 8 SEL Input Voltage “H” (VSELH), SEL Input Voltage “L” (VSELL)
Start from the initial status, set V4 = 0 V. Confirm the DOP pin is in “L”. After that, decreasing the SEL pin’s
voltage gradually, the SEL pin’s voltage when the DOP pin’s voltage is set to “H”; is the SEL input voltage “L”
(VSELL). After that, increasing the SEL pin’s voltage gradually, the SEL pin’s voltage when the DOP pin’s voltage is
set to “L”; is the SEL input voltage “H” (VSELH).
3. CCT pin Internal Resistance, CDT pin Internal Resistance, CIT pin Internal Resistance 1, CIT pin
Internal Resistance 2, CCT pin Detection Voltage, CDT pin Detection Voltage, CIT pin Detection
Voltage, Short circuit Detection Voltage Delay Time (Test circuit 3)
Confirm both COP and DOP pins are in “H” (its voltage level is VDS
× 0.9 V or more) after setting VVMP = VSEL =
VCTLC = VCTLD = VDD, VVINI = CCT = CDT = CIT = VSS, V1 = V2 = V3 = V4 = 3.5 V. (This status is referred to as
initial status.)
3. 1 CCT pin Internal Resistance (RINC)
The CCT pin internal resistance (RINC) is RINC = VDS / ICCT, ICCT is the current which flows from the CCT pin when
setting V1 = 4.7 V from the initial status.
3. 2 CDT pin Internal Resistance (RIND)
The CDT pin internal resistance (RIND) is RIND = VDS / ICDT, ICDT is the current which flows from the CDT pin when
setting V1 = 1.5 V from the initial status.
3. 3 CIT pin Internal Resistance 1 (RINI1)
The CIT pin internal resistance 1 (RINI1) is RINI1 = VDS / ICIT1, ICIT1 is the current which flows from the CIT pin when
setting VVINI = VDIOV1 max. + 0.05 V from the initial status.
3. 4 CIT pin Internal Resistance 2 (RINI2)
The CIT pin internal resistance 2 (RINI2) is RINI2 = VDS / ICIT2, ICIT2 is the current which flows from the CIT pin when
setting VVINI = VDIOV2 max. + 0.05 V from the initial status.
3. 5 CCT pin Detection Voltage (VCCT)
The CCT pin detection voltage (VCCT) is the voltage at the CCT pin when the COP pin’s voltage is set to “L”
(voltage VDS
× 0.1 V or less) after increasing the CCT pin’s voltage gradually, after setting V1 = 4.7 V from the
initial state.
3. 6 CDT pin Detection Voltage (VCDT)
The CDT pin detection voltage (VCDT) is the voltage at the CDT pin when the DOP pin’s voltage is set to “L”
(voltage VDS
× 0.1 V or less) after increasing the CDT pin’s voltage gradually, after setting V1 = 1.5 V from the
initial state.
