DESCRIPTION

100V Half-Bridge Driver with Floating

Grounds and Adjustable Dead-Time

The LTC®7060 drives two N-Channel MOSFETs in a

half-bridge configuration with supply voltages up to

100V. 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 allows the use of large gate capacitance high volt-

age MOSFETs. Additional features include UVLO, Three-

State PWM input, adjustable turn-on/-off delays and

shoot-through protection.
