The IC\'s reset delay function is particularly useful for safely monitoring and restarting automotive systems in the event of an overvoltage or power-on reset event.For industrial applications, the MAX16134MLG+T provides a high degree of reliability for system startup and shutdown. With the integrated power-on reset protection, it is capable of withstanding power supply interruptions and can be used in systems requiring stable system reset and power indication. Additionally, the IC provides precise reset thresholding and voltage monitoring, as well as reset delay, eliminating the need for additional external circuitry.

Working Principle

The main feature of the MAX16134MLG+T is its advanced power reset control, designed for reliable system reset, power indication, and power monitoring in a wide variety of applications. The IC is configured using an internal circuit that utilizes a current source to compare output voltage with its upper and lower voltage thresholds. It then controls the outputs based on this comparison.The MAX16134MLG+T is designed to monitor the VDD voltage and issue a reset signal when the input voltage crosses a predefined threshold. When VDD voltage falls below the reset threshold, the internal circuit triggers the reset output and maintains the reset until the input voltage recovers to its normal operating level. The MAX16134MLG+T also has an open-drain power-good signal output, which indicates when the monitor voltage is within the specified limits.The MAX16134MLG+T also features an adjustable reset delay, allowing the user to specify the minimum amount of time the reset output should remain active. This feature can be used to ensure that all established timing conditions within the system are reset before the system resumes normal operation.

Conclusion

The MAX16134MLG+T is an advanced power reset control IC designed for reliable system reset, power indication, and power monitoring in a wide variety of applications. With its integrated voltage monitor and open-drain power-good indicator, it offers an ideal solution for reliable reset hold-up protection and system startup and shutdown. Furthermore, its adjustable reset delay functionality and level shifting capabilities make it a suitable supervisor for robust and reliable monitoring of various systems.
