MAX6313UK39D2-T

PMIC, or Power Management Integrated Circuit, consists of Supervisors and other power management integrated circuits that control the supply of various circuits within a device or system. MAX6313UK39D2-T is an example of a Supervisory IC, which monitors power supplies for battery-powered systems. In this article, the application field and working principle of MAX6313UK39D2-T will be discussed.

MAX6313UK39D2-T provides integrated backup logic, designed to maintain an external backup supply independent of the main supply. It monitors both the main and backup supply voltages, and switches to the appropriate supply based on their level. This enables the device to maintain power even in the event of a primary power supply failure. The IC is also capable of detecting a low battery voltage condition and signaling to the system.

MAX6313UK39D2-T is suitable for use in battery-powered devices, such as digital still cameras, camcorders, PDAs, and industrial applications. In these devices, MAX6313UK39D2-T is used to ensure continuous operation in the event of a short or long-term power interruption. This feature allows the device to maintain its application state, making it suitable for industrial applications that need no-break power supplies.

The MAX6313UK39D2-T IC integrates a supervisor and an Analog-to-Digital Converter (ADC). The supervisor monitors the main supply voltage and the backup supply voltage, switching between the two based on their level. The ADC monitors the battery voltage level and signals to the system if the voltage drops below a predetermined threshold. The MAX6313UK39D2-T is designed to run from a 3V to 5.5V power supply and can operate in the temperature range of -40°C to +85°C.

The MAX6313UK39D2-T includes an intelligent low-power feature that reduces power consumption when there is no activity on the device. It also includes an adjustable threshold window that allows the IC to switch between the main and backup supply more quickly. This can be adjusted to lower the current consumption in the system.

The primary feature of the MAX6313UK39D2-T is its ability to seamlessly switch between the primary and backup supply based on the supply voltage levels. In addition to this, the IC features various configurable parameters, such as the low voltage threshold and the current allowance limit, to enable custom operation. The IC also features several output capabilities, such as push-pull outputs, open drain outputs, and Schmitt-trigger outputs, that allow for flexibility in the system design.

In conclusion, the MAX6313UK39D2-T is an invaluable tool for battery-powered applications, enabling seamless switching between primary and backup power supplies. It integrates various features that make it suitable for a wide range of applications, from consumer PDAs to industrial applications. With its low current requirement and wide operating temperature range, this IC is an ideal choice for a variety of power management needs.
