FEATURES - 150V Maximum Input Voltage Independent of IC Supply Voltage VCC - 6V to 14V VCC 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 - VCC UVLO and Floating Supply UVLO - Drives Dual N-Channel MOSFETs - Available in Thermally Enhanced 10-LEAD Mini Small Outline Package (MSOP) APPLICATIONS - Industrial Power Systems - Half-bridge DC/DC Converters - Telemunication Power Systems GENERAL DESCRIPTION The LTC7068 is a half-bridge dual N-Channel MOSFET gate driver that operates at up to 150V input voltage and features a supply-independent three-state pulse width modulation (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 shootthrough 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.
