A PMIC Supervisor, or Power Management Integrated Circuit (PMIC), is a specialized integrated circuit that manages power for a wide range of electronic devices and systems. MAX6313UK32D4-T, a highly advanced supervisor from Maxim Integrated, provides a means to monitor, control and regulate the supply voltage and current for a wide variety of applications.

Application Field

The MAX6313UK32D4-T is optimized for use in mobile phones and other handheld systems, networking equipment, sensors and peripherals, as well as active-mode power supplies. It is also suitable for battery-powered applications thanks to its adjustable undervoltage (UV) detection thresholds. It delivers low quiescent current (IQ) and low power dissipation in a bid to extend battery life in portable applications. It can support a range of voltages, including 2.5V, 3V, 3.3V, 5V and 12V, lowering the component count due to its comprehensive range of configuration options.

Working Principle

The MAX6313UK32D4-T supervisor monitors system voltage levels within predetermined thresholds, ensuring that they are neither too high nor too low. When an unacceptable voltage level is detected, the supervisor outputs an active-low reset pulse of sufficient width to reset the system. This reset maintains system stability and prevents the system from malfunctioning. The MAX6313UK32D4-T\'s UV reset threshold is adjustable, allowing it to provide the best possible protection within its operational range.

The MAX6313UK32D4-T supports three types of reset: manual reset, soft reset and power-on reset (POR). It also has factory-programmable timing options, allowing the reset characteristics to be customized to the application at hand. In addition, the MAX6313UK32D4-T provides Precision System Reset Time (PSRT), which is accurate within a few microseconds and remains stable under varying system conditions.

Apart from monitoring and resetting the power supply, the MAX6313UK32D4-T also offers a Watchdog Timer (WDT) that can be used to detect system hangs or malfunctions. The WDT can be programmed to generate a reset pulse if the host processor does not reset it within the specified time duration. It also features open drain, active-low WDT interrupt, which can be used to detect WDT time-outs and other system faults.

The MAX6313UK32D4-T demonstrates Maxim Integrated\'s commitment to providing highly flexible and reliable PMIC supervisors for a wide range of applications. It is optimized for handheld devices, active-mode power supplies, sensors, and peripherals. Its adjustable UV detection thresholds, Precision System Reset Time and WDT demonstrate that it can provide the performance and stability that are necessary for a successful application.
