6.5 Electrical Characteristics

Limits apply over the junction temperature (T_J) range of –40°C to +150°C, unless otherwise stated. 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 = 13.5V.⁽¹⁾

(1) MIN and MAX limits are 100% production tested at 25°C. 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) Non-switching quiescent input current is the current used by the device in open loop. The specified value does not represent the total input current of the system when in regulation.

(3) When the voltage across the C_BOOT capacitor falls below this voltage, the low side MOSFET is turned ON to recharge the boot capacitor.
