PMIC - Supervisors

The MAX6307UK36D4-T is a supervisor manufactured by Maxim Integrated products. It is specifically designed for use in 3.3V, 5V, and 12V systems. The MAX6307UK36D4-T is an ultra-low quiescent current supervisor which provides flexible reset functionality. It is ideal for applications where board space is at a premium, such as industrial and handheld user devices. This device has a wide operating temperature range and is RoHS/WEEE compliant.

Description

The MAX6307UK36D4-T supervisor is a versatile product that can be used to monitor supply voltages, generate reset signals, and keep devices in reset until safe operating conditions exist. It has a low operating current of 4.5µA, adjustable reset threshold voltage range from 1.2V to 2.6V, adjustable reset timeout range from 0.1s to 8s, an active low reset output flag, push-pull or open-drain reset output, and an active low power-good output flag. The MAX6307UK36D4-T features overvoltage protection and reverse battery protection for 3.3V, 5V and 12V systems.

Features and Benefits

• Low operating current: 4.5µA
• Adjustable reset threshold voltage range: 1.2V to 2.6V
• Adjustable reset timeout range: 0.1s to 8s
• Active low reset output flag
• Push-pull or open-drain reset output
• Active low power-good output flag
• Overvoltage protection and reverse battery protection
• Wide operating temperature range
• RoHS/WEEE compliant

Applications

The MAX6307UK36D4-T has various applications that include, but are not limited to, handheld electronic devices, ultrabooks, embedded systems, network storage, factory automation, and medical equipment. Due to its low power operation, it is also ideal for portable applications where board space is at a premium.

Working Principle

The MAX6307UK36D4-T has an adjustable reset threshold voltage, which is monitored by an internal comparator. When the input voltage drops below the preset threshold, the device pulls the reset pin and starts the timeout period. The reset pin will remain asserted until the input voltage rises above the threshold voltage and the reset timeout period has elapsed. A low-to-high transition on the active low reset output flag indicates that the device is out of reset. The active low power-good output flag indicates that the input supply voltage is above the reset threshold. Additionally, the MAX6307UK36D4-T offers overvoltage protection and reverse battery protection.

Conclusion

The MAX6307UK36D4-T is an ultra-low quiescent current supervisor which provides flexible reset functionality for 3.3V, 5V, and 12V systems. It is ideal for applications where board space is at a premium, such as industrial and handheld user devices. This device provides adjustable reset threshold voltage, adjustable reset timeout, active low reset output flag, push-pull or open-drain reset output, and active low power-good output flag. Thanks to the wide operating temperature range and RoHS/WEEE compliance, the MAX6307UK36D4-T is suitable for a wide range of applications.
