7.5 Electrical Characteristics (continued)

Limits apply over operating junction temperature (T_J) range of –40°C to +150°C, unless otherwise stated. Minimum and

Maximum limits⁽¹⁾are specified through test, design or statistical correlation. Typical values represent the most likely

parametric norm at T_J= 25°C, and are provided for reference purposes only. Unless otherwise stated, the following

conditions apply: V_IN= 24 V.

(1) MIN and MAX limits are 100% production tested at 25℃. Limits over the operating temperature range verified through correlation using

Statistical Quality Control (SQC) methods. Limits are used to calculate Average Outgoing Quality Level (AOQL).

(2) The current limit values in this table are tested, open loop, in production. They can differ from those found in a closed loop application.

(3) Not production tested. Specified by correlation by design at 1-A load.

(4) Not production tested. Specified by design.
