These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.

(1) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. DC and AC electrical specifications do not
apply when operating the device beyond its rated operating conditions.
(2) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/Distributors for availability and
specifications.
(3) See Application Information for details regarding current limiting.
(4) The maximum power dissipation must be derated at elevated temperatures and is a function of T_J(max), θ_JA, and T_A. The maximum
allowable power dissipation at any temperature is P_D(max) = (T_J(max) − T_A)/θ_JA, or the number given in the Absolute Ratings, whichever is
lower. The typical thermal resistance from junction to case (θ_JC) is 1.0°C/W and from junction to ambient (θ_JA) is 30°C/W. For ensured
operation T_J(max) = 125°C.
(5) Human-body model, 100 pF discharged through a 1.5 kΩ resistor. Except Bootstrap pins (pins 1 and 11) which are protected to 1000V
of ESD.

Electrical Characteristics ⁽¹⁾
The following specifications apply for V_S = 42V, unless otherwise specified. Boldface limits apply over the entire operating
temperature range, −40°C ≤ T_J ≤ +125°C, all other limits are for T_A = T_J = 25°C.

(1) All limits are 100% production tested at 25°C. Temperature extreme limits are ensured via correlation using accepted SQC (Statistical
Quality Control) methods. All limits are used to calculate AOQL, (Average Outgoing Quality Level).
(2) Output currents are pulsed (t_W < 2 ms, Duty Cycle < 5%).
(3) Selections for tighter tolerance are available. Contact factory.
(4) Regulation is calculated relative to the current sense output value with a 1A load.
