Fast 150V Protected High Side NMOS Static Switch Driver with PassThru

The LTC7000/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 cool-down period, the LTC7000/LTC7000-1 automatically retries.

The LTC7000/LTC7000-1 is available in the thermally-enhanced 16-lead MSOP packages.
