Electrical Characteristics Notes
Note 1:
Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. DC and AC electrical specifications do not apply when op-
erating the device beyond its rated operating conditions.
Note 2:
See Application Information for details regarding current limiting.
Note 3:
The maximum power dissipation must be derated at elevated temperatures and is a function of T
,
θ
, and T
. The maximum allowable power dis-
sipation at any temperature is P
D(max)
=(T
J(max)
T
A
)/
θ
JA
, or the number given in theAbsolute Ratings, whichever is lower. The typical thermal resistance from junc-
tion to case (
θ
JC
) is 1.0C/W and from junction to ambient (
θ
JA
) is 30C/W. For guaranteed operation T
J(max)
= 125C.
Note 4:
Human-body model, 100 pF discharged through a 1.5 k
resistor. Except Bootstrap pins (pins 1 and 11) which are protected to 1000V of ESD.
Note 5:
All limits are 100% production tested at 25C. Temperature extreme limits are guaranteed via correlation using accepted SQC (Statistical Quality Control)
methods. All limits are used to calculate AOQL, (Average Outgoing Quality Level).
Note 6:
Output currents are pulsed (t
W
<
2 ms, Duty Cycle
<
5%).
Note 7:
Regulation is calculated relative to the current sense output value with a 1A load.
Note 8:
Selections for tighter tolerance are available. Contact factory.
