150V High Side N-Channel MOSFET Driver Provides 100% Duty Cycle Capability

The LTC7001 high speed, high side N-channel MOSFET driver operates up to a 150V supply voltage while its internal charge pump fully enhances an external N-channel MOSFET switch, enabling it to remain on indefinitely. The LTC7001’s 1Ω gate driver can drive large gate capacitance MOSFETs with short transition times and 35-ns propagation delays.

 

The LTC7001 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 135V (150V abs max). The LTC7001 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 1000pF load, minimize switching losses. Other features include an adjustable turn-on slew rate and an adjustable overvoltage lockout.

 

The LTC7001 is available in the MSOP-10 package with the leads configured for high voltage spacing. It is available in three operating junction temperature grades of extended and industrial versions from –40 to 125°C, 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 $2.40 each. For more information, visit http://www.linear.com/product/LTC7001
