LTC7004HMSE#TRPBF is specialized in PMIC - Gate Drivers. The application field of this driver includes automotive, aerospace, industrial, and medical applications. It is a high-voltage, high-speed gate driver provides differential drive to power MOSFETs and IGBTs with peak output current ratings up to 6A and voltage ratings up to 1200V. It can also be used for driving isolated gate drives, such as isolated MOSFETs, IGBTs, and opto-couplers, with their gate voltage isolated from the IC ground.

The working principle of LTC7004HMSE#TRPBF area is based on Soft-Turn-On Technology, which features a fast and controllable turn-on transition. During the transition from switching off to switching on, the gate driver has a minimized switching loss which is about 60mJ for a typical 6A IGBT. Also, due to its low supply current of 70mA and its incredibly low quiescent current of 200nA, it can be used in applications with high input speeds such as motor control. It supports slew-rate control, so that it can optimize the transition.

LTC7004HMSE#TRPBF also has protection features such as an Auto-Retry that allows the driver to automatically re-initiate the gate charge cycle in case of over-current conditions. This introduces an additional level of reliability and boosts system performance through auto-fault handling. The driver also offers Over-Temperature Protection (OTP). It uses an internal VREF to detect a programming resistor to identify over-temperature conditions.

Finally, the driver is designed for robustness against noise and RF interference, so it features full CMOS design. It allows fast switching times between Hi-Z to Low-Z, but also offers an interface for low frequency control signals and a clamping network for suppressing transient voltage peaks.

The gate driver LTC7004HMSE#TRPBF is an ideal solution for controlling power MOSFETs and IGBTs at high speed and voltage. It features Soft-Turn-On Technology allowing low-loss switching, and incorporated the Auto-Retry and Over-Temperature Protection features for reliability. Furthermore, it is designed for stability against RF interferences, making it suitable for automotive, aerospace, medical and industrial applications.
