POWER DISTRIBUTION SWITCHES, LOAD DRIVERS, are essential components in any electronic device. They are primarily used as power distributors and voltage regulators, but they also have other applications, such as providing a path for powering off and powering on peripheral components, providing additional power for system reset, providing remote voltage and current control, providing isolation for multiple on-board peripherals and providing additional current for circuit protection. The MIC2045-1BTS-TR is a power management integrated circuit (PMIC) designed for these purposes.

The MIC2045-1BTS-TR is a three-channel power distribution switch and load driver providing high-side and low-side switching, programmable input impedance, and adjustable current and voltage limits. The device consists of a dedicated NMOS and PMOS transistor for each of the two high side switches, plus two low side switches, providing seamless power distribution in applications requiring 0 to 28V and up to 2A of current. A dedicated enable pin is provided to control the enablement of the device, allowing the user to enable or disable the device with a logic level control.

The MIC2045-1BTS-TR’s power distribution feature is a great benefit for providing higher reliability and integrity of the application, as it allows for separation of the power supply rails to different peripherals or subsystems, ensuring efficient power distribution and reduced system noise. It also eliminates the need for circuit protection devices, saving space, weight and cost.

The combination of power distribution and load drivers in the MIC2045-1BTS-TR also makes it suitable for a wide variety of applications, ranging from controlling large DC motors to powering LEDs. With adjustable inrush current limiting and overcurrent protection, the MIC2045-1BTS-TR is suitable for use with sensitive load elements such as FETs, LEDs and relays. Its adjustable drop-out voltage, current and pulse sensitivity can be adjusted to suit the specific power requirements of individual applications, making it a great choice for automotive, industrial, consumer and battery-powered applications.

The MIC2045-1BTS-TR also features several levels of built-in protection circuitry, providing both overcurrent/short circuit and overvoltage/undervoltage protection. The device features a ‘channel fault’ output signal which can be used to detect system faults or device failure. This signal can be used to trigger additional system protection, for example a system reset or the disabling of affected peripherals.

The MIC2045-1BTS-TR is a relatively small device, measuring 4.2mm x 4.2mm and comes in an 8-pin MSOP package, allowing it to fit into small, space-constrained applications. Its low-power consumption makes it an ideal choice for battery-powered applications.

The MIC2045-1BTS-TR is a comprehensive and versatile power distributor and load driver, providing engineers with a highly integrated solution for power distribution and control. Its advanced protection circuitry and easy programming make it well-suited for a wide range of applications, from automotive and industrial to consumer and battery-powered applications.
