6.5 Electrical Characteristics

Minimum and maximum limits 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 = 3.6 V, V_EN = 1.2 V, T_J = 25°C⁽¹⁾

(1) Min and Max limits are 100% production tested at 25°C. Limits over the operating temperature range are specified through correlation using Statistical Quality Control (SQC) methods. Limits are used to calculate the Average Outgoing Quality Level (AOQL).

(2) Typical numbers are at 25°C and represent the most likely parametric norm.

(3) Shutdown current includes leakage current of the high side PFET.

(4) Current limit is built-in, fixed, and not adjustable.
