Power
Linear Technology offers the LTC7004, 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 device’s powerful 1ohm gate driver can easily drive large gate capacitance MOSFETs with very short transition times and 35ns propagation delays, well suited for both high frequency switching and static switch applications.
The device is designed to receive a ground-referenced, low voltage digital input signal and quickly drive a high side N-channel power MOSFET whose drain can be between 0V and 60V (65V abs max). The device operates from a 3.5V to 15V driver bias supply range with an adjustable undervoltage lockout. The fast 13ns rise and fall times, when driving a 1,000pF load, minimize switching losses. Other features include an adjustable turn-on slew rate and an adjustable overvoltage lockout.
