MAX6829SDUT+T

Power Management ICs (PMICs) are specialized microcontrollers that provide power conversion, power control, and power monitoring capabilities. Supervisors, a type of PMIC, act as a safeguard which monitor circuit conditions and protect the system by triggering an action when an undesired condition occurs. The MAX6829SDUT+T is a high-performance and versatile two-pin supervisor IC which was especially developed to protect DRAMs, VRAMs, and ASICs. This article will discuss the application field and the working principle of the MAX6829SDUT+T.

Applications of MAX6829SDUT+T

The MAX6829SDUT+T is widely used in various industries such as automotive, industrial, and consumer electronics. Some of its applications and features include:

• • It is used in embedded systems to detect, during start-up, the over-voltage and over-current conditions for the protection of the system.
• • It features an adjustable threshold and trigger output, which help detect over-voltage and over-current conditions quickly.
• • It is used in smart phones and tablets to protect against short circuit and over-voltage incidents on the battery charge/discharge connections.
• • It is used in industrial, medical, and automotive applications, where it monitors and controls multiple voltage rails.

Working Principle of MAX6829SDUT+T

The MAX6829SDUT+T is a two-pin supervisor IC, meaning that it is powered and reset by the same pin. This makes it a compact and space-saving design, which is ideal for space-constrained systems. The MAX6829SDUT+T contains two comparators which monitor the two input pins, VIN and VOUT. If the voltage level of the input pins exceeds the threshold range, the output will trigger. The output can be set to either active high or active low, and can be used to reset a circuit or signal.

The MAX6829SDUT+T also has an adjustable timeout feature which prevents false triggers when the input voltage is briefly exceeded. This feature is programmable, with a range of 10ms to 4h. The MAX6829SDUT+T also features an enable/disable (EN) input pin, and when this is disabled the output is set to the inactive state, regardless of the input voltage.

The MAX6829SDUT+T has a wide supply voltage range, from 1.8V to 5.5V, and provides protection up to ±40V on the input pins. It is also very energy efficient, consuming less than 1 µA of power during normal operation.

Conclusion

The MAX6829SDUT+T is a versatile two-pin supervisor IC, providing over-voltage and over-current protection to DRAMs, VRAMs, and ASICs. It is space-saving, energy efficient, and has an adjustable timeout feature which prevents false triggers. The MAX6829SDUT+T is widely used across various application fields in consumer electronics, automotive, and industrial systems.
