100V Half-Bridge Driver with Adaptive Shoot-Through Protection

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 VCC supply and floating driver supply that turn off the external MOSFETs when activated. See below for a comparison of the parts in this family.
