Introduction

The MIC2583R-MYQS-TR is an advanced power management integrated circuit (PMIC) developed by Microchip. It is a part of Microchip\'s Hot Swap Controller family and is specifically designed for Hot Swap applications. It provides high-efficiency power monitoring at the load side of the power supply, allowing for accurate voltage, current and temperature readings.

Application Field

The MIC2583R-MYQS-TR is especially suitable for automotive and wireless infrastructure applications, allowing reliable power delivery and monitoring for sensitive hot-swappable components such as processors, memory, FPGAs, or swappable storage devices. The PMIC facilitates diagnosis and fault-tolerant, load-level hot-swapping of components, improving system uptime and diagnostics while meeting stringent protection requirements, including under voltage lockout (UVLO), output current and voltage limits, over temperature protection (OTP), and surge protection. Furthermore, the MIC2583R-MYQS-TR can be used in power systems with multiple power sources, with support for pre-charge sequencing, sequencing, shutdown and sequencing modes. The PMIC also supports application-specific configurations and settings to ensure power system reliability and reduce design costs. It also features wide input voltage range capability and adjustable output voltage capabilities. The MIC2583R-MYQS-TR features built-in field programming to enable rapid prototype development and rapid testing.

Working Principle

The working principle of the MIC2583R-MYQS-TR is based on the hot-swap technology, which allows for a reliable connection of the load through an "intelligent" switch or controller, providing protection against voltage transients, surge current, and electrical overstress. The first stage is the PMIC\'s "pre-charge" (or "activation") stage which enables the power supply to gradually charge the switch capacitor to the predetermined voltage, thus activating the power switch for the desired load. Additionally, the PMIC\'s monitored current and voltage levels provide system protection against over current, over voltage, and over temperature conditions.In the second stage, the PMIC monitors the load voltage, current and temperature values of the power supply, turning the switch off if necessary due to a current, voltage or temperature limit being reached. Finally, the switch capacitor is discharged and the PMIC is ready to repeat the cycle.

Conclusion

The MIC2583R-MYQS-TR is an advanced power management integrated circuit designed for Hot Swap applications, specifically designed for automotive and wireless infrastructure applications. It provides high-efficiency power monitoring at the load side of the power supply, allowing for accurate voltage, current and temperature readings. The working principle of the MIC2583R-MYQS-TR is based on the hot-swap technology, which allows for a reliable connection of the load through an "intelligent" switch or controller, providing protection against voltage transients, surge current, and electrical overstress.
