MIC2564A-1BSM Power Distribution Switches, Load Drivers Application Field and Working Principle

The MIC2564A-1BSM is an integrated power distribution switch and load driver from Micrel. It is an ideal solution for distributing power, driving loads, and providing general purpose power supply configurations for on-board and off-board applications. This integrated power management device can achieve excellent performance in voltage drop, thermal dissipation, and power output efficiency. It is designed to handle up to 3A continuous load currents in the load switch, and the load driver it supports has the ability to drive up to 2A of peak load current.

Key Features

The MIC2564A-1BSM offers a wide range of features, which include:* Robust, cost-effective power distribution switch with adjustable output voltage* Supports up to three load switches and one load driver* Load switch high/low temperature range of 2A @ 3V-5V* High temperature to low temperature range power dissipation range of 0.2* μW/KHz* Superior efficiency in static and dynamic power output * Output voltage accuracy of ±3.3% over temperature* Output current accuracy of ±4.4% over temperature* Low quiescent current when load is off * JEDEC standard package for maximum thermal efficiency

Applications

The MIC2564A-1BSM power distribution switch and load driver is ideal for applications requiring reliable and efficient current sourcing. These applications include, but are not limited to, power supply management, power control, and any other application requiring a reliable and accurate current source. Its superior efficiency in static and dynamic power output makes it a great solution for controlling power output in devices such as LED lighting, video surveillance systems, and laptops, as well as any application requiring accurate current sourcing. In addition, its low quiescent current when the load is off makes it a great choice for battery powered applications.

Working Principle

The MIC2564A-1BSM load switch works by distributing power through the load switch, when a load is connected the load switch automatically turns on and adjusts the output voltage as required. The load switch has an adjustable output voltage range of 3V-5V with an accuracy of ±3.3%, making it ideal for precise control of power distribution.The load driver also works in concert with the load switch, it can drive up to 2 A of peak load current and supports multiple output configurations. The load driver is capable of taking a proprietary PWM signal from an external source, allowing for greater flexibility in controlling output power. It also has an adjustable output current of up to 2A and an accuracy of ±4.4%, allowing for an even more precise control of the output.Overall, the MIC2564A-1BSM integrated power management device provides an efficient power distribution switch and load driver solution for on-board and off-board applications. Its adjustable output voltage and current ranges, along with its excellent efficiency in power dissipation and output, make it a great choice for any application requiring reliable and accurate current sourcing.
