LTC7061 100V Half Bridge Driver with Floating Grounds and Adjustable Dead-Time FEATURES DESCRIPTION n Unique Symmetric Floating Gate Driver Architecture The LTC 7061 drives two N-Channel MOSFETs in a n High Noise Immunity,Tolerates 10V Ground half-bridge configuration with supply voltages up to Difference 100V. Both high-side and low-side drivers can drive the n 100V Maximum Input Voltage Independent of IC MOSFETs with a different ground reference, providing Supply Voltage V excellent noise and transient immunity. CC n 5V to 14V V Operating Voltage CC Its powerful 0.8 pull-down and 1.5 pull-up MOSFET n 4V to 14V Gate Driver Voltage drivers allows the use of large gate capacitance high volt- n 0.8 Pull-Down, 1.5 Pull-Up for Fast Turn-On/Off age MOSFETs. Additional features include UVLO, TTL/ n Adaptive Shoot-Through Protection CMOS compatible inputs, adjustable turn-on/-off delays n Adjustable Dead-Time and shoot-through protection. n TTL/CMOS Compatible Input n For a similar driver in this product family, please refer to V UVLO/OVLO and Floating Supplies UVLO CC n chart below.
