Description
AI
The LTC7067 drives two high-side N-Channel MOSFETs with supply voltages up to 140V. Both drivers can operate with a different ground reference, providing excellent noise and transient immunity. The two drivers are symmetric and independent of each other, allowing complementary or non-complementary switching.Its powerful 0.8Ω pull-down and 1.5Ω pull-up MOSFET drivers allows the use of large gate capacitance high voltage MOSFETs. Additional features include UVLO, TTL/CMOS compatible inputs and fault indicator.See chart below for a similar driver in this product family.PARAMETERLTC7060LTC7061LTC7062LTC7067Input Signal3-State PWMCMOS/TTL LogicCMOS/TTL LogicCMOS/TTL LogicShoot-Through ProtectionYesYesNoNoAbsolute Max Voltage115V115V115V150VVCCFalling UVLO5.3V4.3V4.3V4.3V
