Analog Devices Inc. LTC7068 150V Half Bridge Drivers
Analog Devices Inc. LTC7068 150V Half Bridge Drivers are half-bridge dual N-channel MOSFET gate drivers that operate at up to 150V input voltage and feature supply-independent three-state pulse width modulation (PWM) input logic. Strong 1.3Ω pull-down and 1.6Ω pull-up drive capabilities enable 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 LTC7068 contains undervoltage lockout (UVLO) circuits on both the VCC supply and floating driver supply that turn off the external MOSFETs when activated.
