1Ω Pull-Down, 2.2Ω Pull-Up for Fast Turn-On and
Turn-Off Times with 35ns Propagation Delays
Internal Charge Pump for 100% Duty Cycle
Short-Circuit Protected
Adjustable Current Trip Threshold

gate driver that operates from input voltages up to 60V.
It contains an internal charge pump that fully enhances an
external N-channel MOSFET switch, allowing it to remain
on indefinitely.

Its powerful driver can easily drive large gate capacitances
with very short transition times, making it well suited for
both high frequency switching applications or static switch
applications that require a fast turn-on and/or turn-off time.
Automatic Restart Timer
Open-Drain Fault Flag
Adjustable Turn-On Slew Rate
Gate Driver Supply from 3.5V to 15V
When an internal comparator senses that the switch
current has exceeded a preset level, a fault flag is asserted
and the switch is turned off after a period of time set by
an external timing capacitor. After a cooldown period, the
LTC7003 automatically retries.
