Linear Technology LTC1153CS8 Auto-Reset Electronic Circuit Breaker

The LTC1153CS8 from Linear Technology is a highly reliable auto-reset electronic circuit breaker designed to provide robust protection to electronic systems. This advanced component is housed in an 8-lead SO package, making it a compact solution for a wide range of applications including industrial, automotive, and communication systems.

One of the standout features of the LTC1153CS8 is its auto-reset capability. This function allows the device to automatically restore power to a load after a fault condition has been cleared, reducing downtime and maintenance efforts. The circuit breaker can handle supply voltages ranging from 4.5V to 18V, making it versatile for different power requirements.

The LTC1153CS8 is designed with an internal charge pump that drives an external N-channel MOSFET. This configuration provides a low on-resistance path for the load current, ensuring efficient operation with minimal power loss. The MOSFET can be sized according to the specific current requirements of the application, giving designers flexibility in their system design.

With its overcurrent protection feature, the LTC1153CS8 can detect and respond to overcurrent conditions swiftly, protecting both the load and the power source from potential damage. The trip current is programmable via an external sense resistor, which allows for precise control over the protection threshold. Additionally, the device includes a fault flag output that provides a signal to a microcontroller or other monitoring system when a fault has occurred.

The LTC1153CS8 also includes a timer-controlled automatic retry feature, which reduces the need for manual intervention. After a fault condition causes the breaker to trip, the device will attempt to reset itself after a predetermined time interval, which can be set by an external capacitor. This self-recovery feature enhances the overall reliability of the system it protects.

In summary, the LTC1153CS8 auto-reset electronic circuit breaker from Linear Technology is a sophisticated and adaptable component that offers an efficient and automated solution to protect electronic circuits from overcurrent conditions. Its compact size, flexible design, and robust protection features make it an excellent choice for a variety of applications.
