PMIC - Supervisors

The MAX6314US26D4-T supervisor is a circuit designed to monitor system supply voltages and provide reset output signals to powered circuitry. This device offers an efficient and cost-effective solution for keeping circuits running reliably while also providing additional functionality such as power supply flagging. The MAX6314US26D4-T also includes several other features such as an adjustable reset threshold, reset assertion when supply voltage de-asserts, and a power-good (PG) flag output. These features help to protect the system from problems such as brown-out conditions and holdoffs for power supplies.

Application Field

The MAX6314US26D4-T has found applications in many fields such as military applications, automotive safety systems, portable electronics, and communications systems. Its unique feature set and compact size make it well suited for these applications. The device is particularly well-suited for applications where a reset input is needed but operating space is minimal. Its adjustable reset threshold can help protect circuit components from irregular power up conditions or other power supply issues. It is well suited for use in applications where supply voltages may vary and can provide a reset signal to ensure proper operation upon power up.

Working Principle

The MAX6314US26D4-T operates by monitoring a supply voltage input while also providing a reset signal output. The device compares the value of the supply voltage against a preset threshold and, when the threshold is exceeded, triggers an internal reset circuit. The reset signal is then provided to the signal output of the device. The reset threshold value is adjustable via an external resistor divider. Additionally, the MAX6314US26D4-T includes a power-good (PG) flag output signal that can be used to monitor the power supply. The PG output is low when the supply voltage is above the reset threshold and is open collector otherwise.

The MAX6314US26D4-T is a reliable way to protect powered circuitry from power supply issues. The adjustable reset threshold allows for setting the correct amount of protection depending on the system needs. Additionally, the flexible PG output flag can be used to quickly monitor the status of the power supply. With these features, the MAX6314US26D4-T is a great choice for a wide range of applications.
