Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: See Test Circuit.
Note 3: Does not include tolerance of current sense resistor.
Note 4: The LTC4100E is guaranteed to meet performance specifications
from 0°C to 70°C. Specifications over the –40°C to 85°C operating
temperature range are assured by design, characterization and correlation
with statistical process controls.
Note 5: Current accuracy dependent upon circuit compensation and sense
resistor.
Note 6: CTH is defined as the sum of capacitance on THA, THB and
SafetySignal.
Note 7: The corresponding overrange bit will be set when a HEX value
greater than or equal to this value is used.
