Fast 150V high side n-channel MOSFET driver will run 100% duty cycle

July 10, 2017 // By Graham Prophet
LTC7001 is a high speed, high side N-channel MOSFET driver that operates up to a 150V supply voltage. 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 readily drive large gate capacitance MOSFETs with very short transition times and 35 nsec propagation delays, suited for both high frequency switching and static switch applications.

 

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 13 nsec rise and fall times, when driving a 1000 pF 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. Pricing starts at $2.40 (1000).
