The LTC7003 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.

Evaluation Kits (1)
Demonstration circuit 2749A is a 60V protected, high side switch featuring the LTC7003. The demo board is designed to switch a 14.5A output load from input voltages from 6V to 60V. The wide input range and low shutdown current (1μA typical) make it suitable for automotive, industrial, medical instrument and telecom applications. This board offers a low 45ns (typical) propagation delay, fast switching times (<10ns) and 100% duty cycle operation.
