MIC2045-1BTS Application Field and Working Principle

Micrel Semiconductor, Inc (Micrel) designs, develops and manufactures both analog and mixed-signal ICs, specialized power management components, and RF communication devices. The MIC2045-1BTS, introduced in 2013, is part of the company’s broad power management portfolio and is included in the Power Management Integrated Circuit (PMIC) category. The device is a low-side single output power distribution switch that is designed to provide high-speed load switching for low-voltage, low-power applications. It is suitable for cell phones and many other battery-operated applications, such as digital cameras, games and portable music players.

Overview of MIC2045-1BTS

The MIC2045-1BTS is a single port low-side power switch which allows for high-speed, bidirectional and/or load measuring across a single output. The device also provides an integration of distribution, load drivers, and power switching capability in one integrated design. The MIC2045-1BTS includes a low-side FET, input sensors, and drivers in a 3-pin, SOT-23 package. Maximum operating voltage is 5.5V and it provides on-time of up to 500ns. The device has a low power shutdown mode, tamper detection, and thermal shutdown. The integrated current sensing capability enables in-rush current limiting, ideal for hot-swapping applications. The MIC2045-1BTS is available in an SOT-23 package and is rated to -40°C to + 85°C operation.

Application Field and Working Principle

The MIC2045-1BTS is used for different types of mobile applications, such as mobile phones, smartphones, laptop computers, tablet computers, media players and portable gaming devices. The MIC2045-1BTS also is used for automotive applications including automotive sensor, motor and light bus, transmission control, and multi-use power supply. The MIC2045-1BTS is designed to provide high-speed, bidirectional switching across a single output, which is ideally suited to support the power requirements of such applications.

The MIC2045-1BTS device features a low on-resistance MOSFET switch and a current limiting circuit that can be configured via external components. It also includes an onboard over-temperature limit, which keeps the device active even in extreme operating conditions. The device can also be shut down via an enable pin, which keeps the device in a sleep state if it is not needed. The MIC2045-1BTS also features an input filter, which helps filter out any noise due to switching operation. In addition, the MIC2045-1BTS also provides a low power shutdown mode, tamper detect, and thermal shutdown.

The MIC2045-1BTS is used for load switching applications, providing power switching between the power supply and the load. The device’s on-resistance at nominal voltage of 1Ω*400V can easily be reduced to as low as 0.4 Ohms, allowing for more efficient power switching. The device can be used as a single-channel device or as a multi-channel device, providing both high-speed load switching and bidirectional operation.

The MIC2045-1BTS typically receives the input signal from the power supply and switches its output between the two states based upon the input signal. The device can then use the integrated current sensing capability to measure the output current, providing excellent load accuracy. The device can be used as a load switch, a load driver, or a combination of the two, depending on the application. The MIC2045-1BTS is designed to provide reliable and maximum power switching efficiency, making it an ideal choice for low- power applications.
