LTC7000/LTC7000-1 Fast 150V Protected High Side NMOS Static Switch Driver FEATURES DESCRIPTION n Wide Operating V : 3.5V to 135V (150V Abs Max) The LTC 7000/LTC7000-1 is a fast high side N-channel IN n 1 Pull-Down, 2.2 Pull-Up for Fast Turn-On and MOSFET gate driver that operates from input voltages up Turn-Off Times with 35ns Propagation Delays to 135V. It contains an internal charge pump that fully n Internal Charge Pump for 100% Duty Cycle enhances an external N-channel MOSFET switch, allowing n Short-Circuit Protected it to remain on indefinitely. n Adjustable Current Trip Threshold (LTC7000) Its powerful driver can easily drive large gate capacitances n Current Monitor Output (LTC7000) 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 (LTC7000) n an external timing capacitor. After a cooldown period, the Adjustable Driver Supply V Undervoltage Lockout CC n LTC7000/LTC7000-1 automatically retries. Low Shutdown Current: 1A n CMOS Compatible Input The LTC7000/LTC7000-1 is available in the thermally- n Thermally Enhanced, High Voltage Capable 16-Lead enhanced 16-lead MSOP packages.
