Fast 60V Protected High Side N-Channel MOSFET DriverProvides 100% Duty Cycle Capability

MILPITAS, CA & NORWOOD, MA – July 13, 2017 – Analog Devices, Inc., which recently acquired Linear Technology Corporation, announces the LTC7003, a high speed, high side N-channel MOSFET driver that operates up to a 60V supply voltage. Its internal charge pump fully enhances an external N-channel MOSFET switch, enabling it to remain on indefinitely. The LTC7003’s powerful 1Ω gate driver can easily drive large gate capacitance MOSFETs with very short transition times and 35ns propagation delays, ideal for both high frequency switching and static switch applications.

The LTC7003 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 as high as 60V above ground. The fast 13ns rise and fall times, when driving a 1000pF load, minimize switching losses. The LTC7003 features an adjustable current limit, a current monitoring output, and adjustable overvoltage lockout and enable inputs.

The LTC7003 is available in the MSOP-16 package. Three operating junction temperature grades are available, with extended and industrial versions from –40 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 $2.30 each. For more information, visit www.linear.com/product/LTC7003.
