60V high side N-Channel MOSFET driver has 100% duty cycle
Analog Devices, which now owns Linear Technology, has launched a high speed, high side N-channel MOSFET driver that operates up to a 60V supply voltage with a an internal charge pump that allows it to remain on indefinitely.

The LTC7004’s 1Ω 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). It operates from a 3.5V to 15V driver bias supply range with an adjustable undervoltage lockout and 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.

The LTC7004 is available in the MSOP-10 package with pins configured for high voltage spacing. It is available in three operating junction temperature ranges of extended and industrial versions from –40°C to 125°C, a high temperature automotive version from –40°C to 150°C and a military grade from –55°C to 150°C. The 1,000-piece price starts at $2.05 each.
