High Side Mosfet Driver Internal Charge Pump

The ltc7000 is a fast protected high side n channel mosfet gate driver that contains an internal charge pump allowing the external n channel mosfet to stay on indefinitely.

High side mosfet driver internal charge pump.

The ltc 7001 is a fast high side n channel mosfet gate driver that operates from input voltages up to 135v. Norwood ma analog devices inc which recently acquired linear technology corporation announces the ltc7001 a high speed high side n channel mosfet driver that operates up to a 150v supply voltage. The mic5021 can also operate as a circuit breaker with or without automatic retry. It contains an internal charge pump that fully enhances an external n channel mosfet switch allowing it to remain on indefinitely.

The ltc7003 s powerful 1ω gate driver can easily drive large gate capacitance mosfets. The mic5019 operates from a 2 7v to 9v supply and generates gate voltages of 9 2v from a 3v supply and 16v from a 9v supply. Its internal charge pump fully enhances an external n channel mosfet switch enabling it to remain on indefinitely. In high side configurations the source voltage of the mosfet approaches the supply voltage when switched on.

An internal charge pump drives the gate output higher than the driver supply voltage and can sustain the gate voltage indefinitely. An internal charge pump boosts the gate drive voltage above the positive rail fully enhancing an n channel mos switch with no external components. The ltc 7001 is a fast high side n channel mosfet gate driver that operates from input voltages up to 135v. An internal zener diode limits the gate to source voltage to a safe level for standard n channel mosfets.

The mic5021 high side mosfet driver is designed to operate at frequencies up to 100 khz 5 khz pwm for 2 to 100 duty cycle and is an ideal choice for high speed applications such as motor control smps switch mode power supplies and applications using igbts. Its internal charge pump fully enhances an external n channel mosfet switch enabling it to remain on indefinitely. Analog devices inc which recently acquired linear technology corporation announces the ltc7003 a high speed high side n channel mosfet driver that operates up to a 60v supply voltage its internal charge pump fully enhances an external n channel mosfet switch enabling it to remain on indefinitely. The ltc1156 quad high side gate driver allows using low cost n channel fets for high side switching applications.
