NOTES:
1.Capability measured by forcing the Output to 2.0 V with Current Sense pin (IS) open while measuring the Output current to ground.
2.Measured by clamping the output to that output voltage with IS pin to ground; then increasing V
D
from 6.0 to 18 V and measuring output leakage
current to ground.
3.Output Clamp voltage with reference to ground while forcing 10 mA into the Dynamic Clamp pin (CL).
4.Output Clamp impedance measured with I
CL
= 11
±
1.0 mA into the Dynamic Clamp pin (CL) and noting the corresponding Output Clamp Voltage
change (Z
=
V
/
I
).
5.Dwell is defined as Run Mode Down Current divided by the Run Mode Up Current times the Ramp Control Current Ratio and is calculated from other
measured characteristics as defined above.
6.Set the V
voltage to 1.5 V; Ramp V
CR
voltage from 1.8 to 2.2 V in 0.02 V increments and note the Ramp voltage (V
CR
) which causes the Output
voltage to go > 1.0 V; V
CRO
= 2.0 V – V
CR
