DESCRIPTION

The LTC®7000/LTC7000-1 is a fast high side N-channel

MOSFET gate driver that operates from input voltages up

to 135V. 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.

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

LTC7000/LTC7000-1 automatically retries.

The LTC7000/LTC7000-1 is available in the thermally-

enhanced 16-lead MSOP packages.
