The MIC2026-2YM-TR is a single power distribution switch and load driver used in power supply management for portable applications. It provides a precise switchable current for driving LED backlight in LCD panels, power saving and thermal management in processor-based systems, and other current-driven devices up to 600mA. An integrated low-dropout regulator allows for seamless voltage distribution to low-power devices, even when the system supply voltage is significantly lower than the device voltage. In the event of system over-current conditions, the MIC2026-2YM-TR will automatically shut down, preventing damage to the device and the system. The MIC2026-2YM-TR is available in a compact 2-pin DFN package and is also qualified for automotive applications.

The MIC2026-2YM-TR is a dual-channel, low-side power switch with two independent channels capable of switching up to 600mA of current per channel. To enable efficient current-carrying capability, the MIC2026-2YM-TR features an integrated LDO controller, allowing for efficient power distribution across the two channels. The device also features under-voltage and over-current protection to protect against abnormal conditions. In the event of an over-current condition, the device will automatically shut down to protect the system and the device itself. As a result, the MIC2026-2YM-TR is well-suited for use in applications with stringent timely, voltage and current requirements.

The MIC2026-2YM-TR works by converting a high-voltage, low-current input supply into two high-current, low-voltage outputs. The device consists of an integrated power switch, an internal regulator, and an over-current protection circuit. The high-voltage input is supplied to the regulator, which then generates a regulated voltage (V REG ), which is supplied to both channels’ outputs. The switch, in turn, takes the regulated voltage (V REG ) and uses it to drive the two outputs. The two switches turn on/off when the respective channels’ input signal is high or low. If a current greater than the preset current (I MAX ) is drawn from the outputs, the over-current protection circuit shuts down the device automatically.

The MIC2026-2YM-TR offers automotive-grade features that enables the device to withstand harsh electrical environments. The device is able to operate over a wide temperature range of -40°C to +105°C, ensuring reliable operation in a variety of applications. The MIC2026-2YM-TR also features an over-voltage protection circuit that monitors the voltage at the device’s input, automatically shutting down the device in the event of an over-voltage condition. The device also comes with scavenging features that remove charge pump leakage current, allowing it to provide a constant flow of current.

The MIC2026-2YM-TR is a highly integrated device that is capable of providing precise current distribution to low power-consuming devices, even when the system voltage is significantly lower than the device voltage. The device also offers added protection from over-voltage, over-current, and thermal protection, making it suitable for a variety of electronic applications. The device is available in a compact 2-pin DFN package and is also qualified for automotive applications, making it an ideal choice for use in portable applications.
