Absolute Maximum Ratings
(1)
Current into VCC (100 µs pulse) 100 mA
OUT, PGD to VEE -0.3V to 100V
UVLO, OVLO to VEE -0.3V to 17V
SENSE to VEE -0.3V to +0.3V
ESD Rating, Human Body Model
(2)
2kV
Storage Temperature -65°C to +150°C
Junction Temperature +150°C
(1) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for
which the device is intended to be functional, but do not ensure specific performance limits. For specifications and conditions see the
Electrical Characteristics.
(2) The human body model is a 100 pF capacitor discharged through a 1.5 kΩ resistor into each pin.
Operating Ratings
Current into VCC
(1)
2 mA (min)
OUT Voltage above VEE 0V to 80V
PGD Off Voltage above VEE 0V to 80V
Junction Temperature −40°C to +125°C
(1) Maximum continuous current into VCC is limited by power dissipation and die temperature. See the Thermal Considerations section.
Electrical Characteristics
Limits in standard type are for T
J
= 25°C only; limits in boldface type apply over the junction temperature (T
J
) range of -40°C
to +125°C. 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: I
CC
= 2 mA, OUT Pin = 48V above VEE, all voltages are with respect to VEE. See
