Description

The LTC®7003 is a fast high side N-channel MOSFET 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.

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.

The LTC7003 is available in the thermally-enhanced 16-lead MSOP package.
