High Speed, High Side N-Channel MOSFET Driver: LTC7004

September 7, 2017

Analog Devices Inc., which recently acquired Linear Technology Corporation, announces the LTC7004, a high speed, high side N-channel MOSFET driver that operates up to a 60 V supply voltage. Its internal charge pump fully enhances an external N-channel MOSFET switch, enabling it to remain on indefinitely. The LTC7004’s powerful 1 Ω gate driver can easily drive large gate capacitance MOSFETs with very short transition times and 35 ns propagation delays, well suited for both high frequency switching and static switch applications.

The LTC7004 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 0 and 60 V (65 V abs max). The LTC7004 operates from a 3.5 to 15 V driver bias supply range with an adjustable undervoltage lockout. The fast 13ns rise and fall times, when driving a 1,000 pF 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. For more information visit www.linear.com/product/LTC7004.
