Introduction

The MAX6388XS18D3-T is a highly integrated, ultra-low-power MOSFET power switch specifically designed to provide inrush current limiting, over-voltage protection, and system reset. This supervisor is available in space-saving 5 mm x 5 mm or 6 mm x 6 mm packages. The MAX6388XS18D3-T can limit the inrush current during start-up and protect the system from over-voltage conditions. It features an internal temperature sensor to help guard against over-temperature conditions and a time-out reset feature to help prevent lock-up conditions. The MAX6388XS18D3-T can provide system reset programmability and can be configured to provide system reset upon the detection of an over-voltage, over-temperature, or time-out condition. The MAX6388XS18D3-T is available in commercial temperature range of 0°C to 70°C.

Application Field of MAX6388XS18D3-T Supervisors

The MAX6388XS18D3-T is a versatile supervisor IC that integrates both reset and inrush current limiting in a single device. It is an ideal solution for applications including automotive (including dashboard and infotainment systems), communications, consumer electronics, heavy industrial equipment, instrumentation, medical devices, networking, and portable electronics. Additionally, this supervisory IC is used in low-power systems with few components due to its low quiescent current.

Working Principle of MAX6388XS18D3-T

The MAX6388XS18D3-T integrates both reset and inrush current limiting in a single device. It utilizes three key components that are essential to its functionality: an N-channel MOSFET, an adjustable voltage delay, and a resistor-programmable reset timeout circuit.The N-channel MOSFET acts as an on/off switch in the circuit. When the circuit is powered on, the Arduino acts as the voltage source and sets the MOSFET to an on state, allowing current to flow into the circuit. The adjustable voltage delay monitors the voltage across the circuit and makes sure it stays within a specified range of the demanded voltage. If the voltage exceeds the predefined range, the MOSFET is shutdown and the power supply is disconnected from the circuit.The resistor-programmable reset timeout circuit performs two key functions. First, it sets the time duration for the system reset. If a fault is detected, the circuit sends a reset signal with a duration equal to the set time. Secondly, the timeout circuit helps prevent system lockups by restarting the system if it remains inactive after a predetermined amount of time.

Conclusion

The MAX6388XS18D3-T is an ultra-low-power, highly integrated MOSFET power switch specifically designed to provide inrush current limiting, over-voltage protection, and system reset. This supervisor is well suited for applications in automotive, communications, consumer electronics, heavy industrial equipment, instrumentation, medical devices, networking, and portable electronics. Its working principle is based on the integration of an N-channel MOSFET, an adjustable voltage delay, and a resistor-programmable reset timeout circuit. The MAX6388XS18D3-T is a convenient, single-chip solution for applications in need of over-voltage, over-temperature, or time-out reset protection.
