6V to 14V V_CC and Bottom Gate Driver Voltage
4V to 14V Top Gate Driver Voltage
1.3Ω Pull-Down, 1.6Ω Pull-Up
Adaptive Shoot-Through Protection
Three-State PWM Input with Enable Pin
V_CC UVLO and Floating Supply UVLO
Drives Dual N-Channel MOSFETs
Available in Thermally Enhanced 10-LEAD MSOP Package

The LTC7065 is a half-bridge dual N-Channel MOSFET gate driver that operates at up to 100V input voltage and features a supply independent three-state PWM input logic.

The strong 1.3Ω pull-down and 1.6Ω pull-up drive capability can drive large gate capacitances of high-voltage MOSFETs with short transition times in high switching frequency applications. The adaptive shoot-through protection is designed for optimized efficiency and MOSFET cross-conduction protection.

The LTC7065 contains undervoltage lockout circuits on both the V_CC supply and floating driver supply that turn off the external MOSFETs when activated. See below for a comparison of the parts in this family.

Product Details

The EVAL-LTC7065-AZ evaluation circuit features LTC7065 driving two N-channel MOSFETs in a half-bridge configuration. The PWM input control is 5V logic compatible and controls both gate outputs, with one output being a complement of the other. The evaluation board has several unpopulated PCB pads to help facilitate the user in customizing the board for their application.

The LTC7065 driver has powerful 1.2Ω pull-down and 1.6Ω pull-up MOSFET drivers driving two 100V Nchannel MOSFETs.
