ADI Releases MOSFET Driver Capable of Operating at 150V Supply Voltage

Suitable for high-frequency switching and contactless switch applications

Analog Devices announced the release of the LTC7001, a high-speed high-side N-channel MOSFET driver capable of operating up to a supply voltage of 150V.

The internal charge pump of this product enables the external N-channel MOSFET switch to be fully driven and kept in an always-on state. The LTC7001's powerful 1Ω gate driver can drive MOSFETs with high gate capacitance within very short switching times and a propagation delay of 35ns, making it ideal for high-frequency switching and static switch applications.

The LTC7001 receives a ground-referenced low-voltage digital input signal and rapidly drives a high-side N-channel power MOSFET, wherein the drain voltage of the MOSFET is allowed from 0V to 135V (maximum 150 abs).

The LTC7001 operates within a driver bias supply voltage range of 3.5V to 15V with an adjustable undervoltage lockout function. Since the rise and fall speeds are very fast at 13ns, switching losses can be reduced when driving a 1,000pF load. In addition, features such as an adjustable turn-on slew rate and an adjustable overvoltage lockout are included.

The LTC7001 is available in an MSOP-10 package with pins removed for high-voltage spacing. This product is available in three temperature grades: an industrial version with an extended temperature range of –40°C to 125°C, a high-temperature automotive version of –40°C to 150°C, and a military version of –55°C to 150°C.
