Introduction to MIC2591B-2YTQ-TR
The MIC2591B-2YTQ-TR is a Hot Swap Controller from the MIC2591B series, one of Microchip Technology’s family of Power Management and Hot Swap Controllers. This series is designed to provide system architects with a cost-effective solution that enables intelligent power sequencing, current limiting and fault protection. The MIC2591B-2YTQ-TR, in particular, has some additional features that make it well-suited to applications that require a large current capacity and robust protection capabilities.
Application Field
The MIC2591B-2YTQ-TR is well-suited to applications that require a large current capacity, robust protection capabilities, and minimize total system cost. It is often used in high-power industrial applications, such as telecommunications networks and data centers. Other applications can include notebook PC power supplies, high-performance video cards, and server backplanes.
MIC2591B-2YTQ-TR is also ideal for use as a Hot Swap controller in systems that require intelligent power sequencing, current limiting and fault protection. These systems can include any number of devices such as digital signal processors, FPGAs and ASICs. Its active current limit accuracy, high current capacity and fast ramp rates provide optimal system protection, reducing the risk of system damage or downtime due to over current conditions.
Working Principle
The MIC2591B-2YTQ-TR is a high-voltage current limited Hot Swap controller. It has two main operation modes: active current limiting and linear current limiting. In the active current limiting mode, the controller monitors the supplied power and, in the event of an over-current occurring, the current through the supply is limited to a maximum value set by the user. In the linear current limiting mode, the controller limits the current to a constant linear rate, protecting the device from current surges and spikes, without the need for complex control or programming.
The MIC2591B-2YTQ-TR also incorporates an independent, temperature-compensated under-voltage lockout (UVLO) circuit. This feature, which is triggered when the voltage at VIN falls below a predetermined level, provides an additional layer of protection by disconnecting the load from the power supply, preventing excessive current from flowing into the device.
The device provides an integrated I2C (inter-integrated circuit) interface, enabling the user to get feedback from the MIC2591B-2YTQ-TR on the current, voltage, and temperature conditions of the system. Using this feedback, the user can program and monitor the device and adjust it to suit their requirements.
Conclusion
The MIC2591B-2YTQ-TR is well-suited to applications that require a large current capacity, robust protection capabilities, and minimize total system cost. With its active current limit accuracy, high current capacity, fast ramp rates, and integrated temperature-compensated under-voltage lockout circuit, the MIC2591B-2YTQ-TR provides superior system protection and power management to enable intelligent power sequencing, current limiting and fault protection. The I2C interface provides the user with a flexible means to program and monitor the MIC2591B-2YTQ-TR device and adjust it to suit their requirements.
