LTC7003 Fast 60V Protected High Side NMOS Static Switch Driver FEATURES DESCRIPTION n Wide Operating V : 3.5V to 60V The LTC 7003 is a fast high side N-channel MOSFET IN n 1 Pull-Down, 2.2 Pull-Up for Fast Turn-On and gate driver that operates from input voltages up to 60V. Turn-Off Times with 35ns Propagation Delays It contains an internal charge pump that fully enhances an n Internal Charge Pump for 100% Duty Cycle external N-channel MOSFET switch, allowing it to remain n Short-Circuit Protected on indefinitely. n Adjustable Current Trip Threshold Its powerful driver can easily drive large gate capacitances n Current Monitor Output with very short transition times, making it well suited for n Automatic Restart Timer both high frequency switching applications or static switch n Open-Drain Fault Flag applications that require a fast turn-on and/or turn-off time. n Adjustable Turn-On Slew Rate n When an internal comparator senses that the switch Gate Driver Supply from 3.5V to 15V n current has exceeded a preset level, a fault flag is asserted Adjustable V Undervoltage and Overvoltage IN and the switch is turned off after a period of time set by Lockouts n an external timing capacitor. After a cooldown period, the Adjustable Driver Supply V Undervoltage Lockout CC n LTC7003 automatically retries. Low Shutdown Current: 1A n CMOS Compatible Input The LTC7003 is available in the thermally-enhanced n Thermally Enhanced, High Voltage Capable 16-Lead 16-lead MSOP package.
