Analog Devices Inc. LTC7060 Half Bridge Driver

Analog Devices LTC7060 Half Bridge Driver drives N-channel MOSFETs in a half-bridge configuration with supply voltages up to 100V. It features supply independent 3-state PWM input logic. The unique floating architecture makes the gate driver outputs robust and less sensitive to ground noise. The symmetric design allows the half-bridge switching node to be inverting or non-inverting of the input logic. With 0.8Ω pull-down and 1.5Ω pull-up capability, the strong outputs easily drive the large gate capacitances of high voltage MOSFETs with very short transition times. The adjustable turn-on and turn-off delays allow system optimization for high efficiency and reliability. Adaptive shoot-through protection prevents current resulting from MOSFET cross-conduction. Undervoltage lockout (UVLO) circuits on both the VCC supply and floating driver supplies turn off corresponding external MOSFETs and pull down the FLT pin when an undervoltage condition is present.
