Note 1: Tested with Test Circuit 1.
Note 2: Tested with Test Circuit 2.
Note 3: Sense resistor R
Note 4: Applies to 16-pin only. 8-pin packages are guaranteed but not
tested at – 40 C.
Note 5: Current ( 700 A) flows into the pins during normal operation and
also when an external shutdown signal on the V
Current decreases to 200 A and flows out of the pins when external
shutdown holds the V
input voltage collapses. See external Shutdown in Applications Information
section.
Note 6: A linear interpolation can be used for reference voltage
specification between 0 C and – 40 C.

Note 7: Commercial grade device specifications are guaranteed over the
0 C to 70 C temperature range. In addition, commercial grade device
specifications are assured over the –40 C to 85 C temperature range by
design or correlation, but are not production tested.
Maximum allowable ambient temperature may be limited by power
dissipation. Parts may not necessarily be operated simultaneously at
maximum power dissipation and maximum ambient temperature.
Temperature rise calculations must be done as shown in the Applications
Information section to ensure that maximum junction temperature does
not exceed the 125 C limit. With high power dissipation, maximum
ambient temperature may be less than 70 C.
Note 8: Industrial grade device specifications are guaranteed over the
– 40 C to 85 C temperature range.
Note 9: 91% maximum duty cycle is guaranteed by design if V
(see Figure 8 in Application Information) is kept between 3V and 5V.
