Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2:
The LTC7001 is tested under pulsed load conditions such that
T
J
≈ T
A
. The LTC7001E is guaranteed to meet performance specifications
from 0°C to 85°C. Specifications over the –40°C to 125°C operating
junction temperature range are assured by design, characterization and
correlation with statistical process controls. The LTC7001I is guaranteed
over the –40°C to 125°C operating junction temperature range, the
LTC7001H is guaranteed over the –40°C to 150°C operating junction
temperature range and the LTC7001MP is tested and guaranteed over the
–55°C to 150°C operating junction temperature range.
High junction temperatures degrade operating lifetimes; operating lifetime
is derated for junction temperatures greater than 125°C. Note that the
maximum ambient temperature consistent with these specifications is
determined by specific operating conditions in conjunction with board
layout, the rated package thermal impedance and other environmental
factors.

ELECTRICAL CHARACTERISTICS
Note 3:
The junction temperature (T
J
, in °C) is calculated from the ambient
temperature (T
A
, in °C) and power dissipation (P
D
, in Watts) according to
the formula:
T
J
= T
A
+ (P
D
•
θ
JA
), where
θ
JA
is 45°C/W.
Note 4:
This IC includes over temperature protection that is intended to
protect the device during momentary overload conditions. The maximum
rated junction temperature will be exceeded when this protection is active.
Operation above the specified absolute maximum operating junction
temperature may impair device reliability or permanently damage the
device.
Note 5:
Dynamic supply current is higher due to the gate charge being
delivered at the switching frequency. See Applications Information.
Note 6:
Do not apply a voltage or current source to these pins. They must
be connected to capacitive loads only; otherwise permanent damage may
occur.
Note 7:
Total supply current is the sum of the current into the VCC and TS
pins.

PIN FUNCTIONS
V
CC
(Pin 1):
Main Supply Pin. A bypass capacitor with a
minimum value of 0.1µF should be tied between this pin
and GND.
V
CCUV
(Pin 2):
V
CC
Supply Undervoltage Lockout. A
resistor on this pin sets the reference for the Gate Drive
undervoltage lockout. The voltage on this pin in the range
of 0.5V to 1.5V is multiplied by seven to be the undervolt-
age lockout for the Gate Drive (V
CC
pin). Short to ground
to set the minimum gate drive UVLO of 3.5V. Leave open
to set gate drive UVLO to 7.0V
GND (Pin 3, Exposed Pad Pin 11):
Ground. The exposed
pad must be soldered to the PCB for rated electrical and
thermal performance.
INP (Pin 4):
Input Signal. CMOS compatible input refer-
ence to GND that sets the state of TGDN and TGUP pins
(see Applications Information). INP has an internal 1MΩ
