Power Management IC (PMIC) has become indispensable for modern devices due to their ability to efficiently manage power utilization and conservation. One of the most popular type of PMICs is the supervisor IC, an integrated solution designed to monitor a device\'s power and reset it when it falls below a certain level or fails.One of the most widely used and reliable supervisor solutions is the MAX6367PKA26+T, developed by Maxim Integrated. This IC combines a precision voltage supervisor, power-on reset generator and a low dropout linear-regulator with extremely low quiescent current.

The MAX6367PKA26+T has a wide variety of applications in the modern market, from circuit protection and resetting to reliable power supply monitoring.

Applications

• Backup battery monitoring and protection.
• System reset, power sequencing and voltage supervision.
• Input voltage monitoring and system reset.
• Power-on reset for microcontrollers, DSPs and FPGAs.

The MAX6367PKA26+T is widely employed in automotive applications such as monitoring the battery voltage and protecting circuits from overvoltage. It is also used in industrial and wearable applications.

Working Principle

The MAX6367PKA26+T is an advanced supervisor IC which uses a voltage reference (VREF) to monitor an adjustable voltage threshold (VTH). When the monitored voltage drops below VTH, the IC signals an error condition, often through an active-low reset pin. The IC can also be used to detect high voltage surge and will generate an alert or reset the system in response.

The MAX6367PKA26+T includes an internal linear regulator (L-REG) which operates over a wide voltage range and is able to output a stable voltage even when the input voltage is varied significantly. The linear regulator has very low quiescent current, making it suitable for battery operated devices.

The MAX6367PKA26+T has several protection features, such as Improved EMI immunity and reverse current protection, which ensure reliable operation in extreme conditions. It contains a thermal shutdown system that disables the L-REG if the IC\'s temperature rises above a certain threshold. This helps protect the IC from thermal damage and offers additional safety in case of unforeseen conditions.

The MAX6367PKA26+T has a wide range of operating temperature from -40°C to +125°C, meaning it can be used in extreme temperatures. It is also RoHS compliant and is packaged in a small 4mm x 4mm, 20-pin TQFN package making it suitable for modern, space-constrained designs.

Conclusion

The MAX6367PKA26+T is a highly integrated and reliable supervisor IC solution designed to monitor voltages and protect circuits from damage. It features a precision voltage supervisor, power-on reset generator, low dropout linear regulator and several protection features. With its wide operating temperature and small package size, the MAX6367PKA26+T can be used in a variety of applications, from automotive, industrial and wearable devices. It is a cost-effective, reliable and efficient power management solution for modern devices.
