Its internal charge pump enhances an external N-channel MOSFET switch, enabling it to remain on indefinitely. A powerful 1Ω gate driver can easily drive large gate capacitance MOSFETs with very short transition times and 35ns propagation delays, and makes the device suitable for both high frequency switching and static switch applications.
The LTC7001 has been 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). It operates from a 3.5V to 15V driver bias supply range with an adjustable under-voltage 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 device 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.
