Analog Devices, which recently acquired Linear Technology Corporation, announced the LTC7001, a high speed, high side N-channel MOSFET driver that operates up to a 150 V supply voltage. Its internal charge pump fully enhances an external N-channel MOSFET switch, enabling it to remain on indefinitely. The chip’s powerful 1 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 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 0 V and 135 V (150 V absolute maximum). It operates from a 3,5 V to 15 V driver bias supply range with an adjustable under-voltage lockout. The fast 13 ns rise and fall times, when driving a 1000 pF load, minimise switching losses. Other features include an adjustable turn-on slew rate and an adjustable overvoltage lockout.
The IC 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°C to 125°C, high temperature automotive version from –40 C to 150°C and a military grade from –55°C to 150°C.
