VCA = VCR = VCS = Open, VST = 0 V) Measure VS

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 VD 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 ICL = 11 ± 1.0 mA into the Dynamic Clamp pin (CL) and noting the corresponding Output Clamp Voltage

change (ZCL = ∆VCL/∆ICL).

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 VCR voltage to 1.5 V; Ramp VCR voltage from 1.8 to 2.2 V in 0.02 V increments and note the Ramp voltage (VCR) which causes the Output

voltage to go > 1.0 V; VCRO = 2.0 V – VCR.
