3 / 20 page LTC4001-1 3 40011fa ELECTRICAL CHARACTERISTICS 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: Operation with current limited wall adapters is allowed down to the undervoltage lockout threshold. Note 3: The LTC4001E-1 is guaranteed to meet performance specifica- tions from 0°C to 85°C. Specifications over the – 40°C to 85°C operating temperature range are assured by design, characterization and correlation with statistical process controls. The l denotes the specifications which apply over the full operating temperature range, otherwise specifications are at TA = 25°C. VIN = 5V, VEN = 0V, RPROG = 549Ω, RIDET = 549Ω, unless otherwise specified.

Junction temperature will exceed 125°C when overtemperature protection is active. Continuous operation above the specified maximum operating junction temperature my impair device reliability. |
