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.

Product Details

The EVAL-LTC7067-AZ features the LTC7067 in a flexible configuration as a non-synchronous step-down or as a non-synchronous step-up converter. EVAL-LTC7067-AZ also has a default set up to test LTC7067 only with a load capacitor. As both Gate returns are floating, LTC7067 can be configured to drive dual-high side MOSFET, or to drive high-side and low-side MOSFET. Typical performance is shown in Table 1 in the user guide.

This demo board features LTC7067, 150V Dual high-side MOSFET gate driver with overvoltage and undervoltage protections in a 12-pin MSE package. Refer to the LTC7067 data sheet for more detailed information.
