Overview of the LTC1165CS8#PBF

The LTC1165CS8#PBF is a dual HIGHside driver, low side driver, high/low driver and inverter PMIC, belonging to the LTC1165 off-the-shelf family. It is designed to deliver protection levels similar to that of internationally recognized safety standards such as CSA, IEC, UL, and other certification requirements, offering integrated gate protection both in operand and source lines, short circuit protection and thermal shut-down protection. It is ideal for gate driving applications in various devices such as gate switches of bridge drivers, power relays, power FETs, as well as many other gate drive applications.

Applications

The LTC1165CS8#PBF is an ideal device for gate driving in motor control systems, display drivers, and other gate drive applications. It is suitable for a wide range of applications including motor controls, switching power supplies, instrumentation and process control systems, robotics and industrial automation, display driver systems, etc.The device is particularly suited for DC motor speed and torque control applications due to its high-current output capability and fast rise/fall times. The LTC1165CS8#PBF allows designers to increase the frequency of PWM commands and to provide greater control over speed, torque and position with high performance and minimal power dissipation.The device is also well suited for LED lighting systems, as its low voltage operation, low power dissipation, low current consumption and fast rise/fall times make it perfect for these applications.

Working Principle

The LTC1165CS8#PBF is an externally powered, low voltage driver that works on the principle of dynamic MOSFET operation. In operation, the LTC1165CS8#PBF will detect the state of the gate drive signal and will then adjust the gate voltage and current to the desired level for the particular application.The gate voltage and current control is achieved by the internal logic of the device, which sense the Vgs of the MOSFET, and the output current limit of the controller. If the Vgs of the MOSFET is close to the threshold voltage, the LTC1165CS8#PBF will boost the gate voltage to start the MOSFET operation, and thus set the proper gate drive current to the device.When the MOSFET is operating in the saturation region, the LTC1165CS8#PBF will reduce the output current limit and the gate voltage to ensure that the power dissipation is within the limits of the device.This entire process is controlled by an integrated control loop inside the device, which is designed to ensure the proper operation of the MOSFET under various operating conditions, while also providing protection against short-circuiting, thermal runaway, and out-of-range currents.

Conclusion

The LTC1165CS8#PBF is a high performance, low power, and user-friendly PMIC device that is ideal for gate drive applications in motor control systems, display drivers, and other gate drive application. Its small compact design, transient protection features, and ability to deliver fast rise and fall times make it suitable for many applications, including high performance motor control, switching power supplies, LED lighting systems, and many other applications. Its integrated gate protection and high current handling features make it suitable for driving a wide range of MOSFETs and high side switches in most motor control, display and other gate drive applications.
