The LTC7066 drives two N-Channel MOSFETs in a half-bridge configuration with supply voltages up to 140V. Both high-side and low-side drivers can drive the MOSFETs with a different ground reference, providing excellent noise and transient immunity.

Its powerful 0.8Ω pull-down and 1.5Ω pull-up MOSFET drivers allow the use of large gate capacitance high voltage MOSFETs. Additional features include UVLO, TTL/CMOS compatible inputs, adjustable turn-on/-off delays, and shoot-through protection.

Product Details

The EVAL-LTC7066-AZ evaluation circuit is a half-bridge driver that drives two N-channel MOSFETs. The two 5V logic-compatible PWM inputs independently drive each of the two N-channel gate outputs to each MOSFET. The eval kit has several unpopulated PCB pads to help facilitate the user in customizing the board for their application.

The LTC7066 driver has a powerful 0.8Ω pull-down and 1.5Ω pull-up MOSFET drivers driving two 150V N-channel MOSFETs. The gate drivers on the LTC7066 are capable of driving MOSFETs with different ground references; however, this eval kit has these ground references committed.
