MIC94080YFT-TR

The MIC94080YFT-TR is an integrated, low-power Power Distribution Switch and Load Driver designed for a wide variety of automotive and industrial applications. With an impressive array of features, the MIC94080YFT-TR is an extremely versatile and reliable Power Distribution Switch, Load Driver and voltage regulator. This article will discuss the application field, working principle and key features of the MIC94080YFT-TR.

Application Field

The MIC94080YFT-TR is ideal for a variety of automotive and industrial applications. The device is well suited for power supply sequencing applications in automotive engine controllers, fuel injectors, start/stop systems and pump controllers. It can be used as an integrated low side or high side switch or load driver in automotive powertrain controls, instrument clusters, HVAC systems and audio systems. In addition, the MIC94080YFT-TR is also suitable for on-board charging systems, industrial automation and Machine-to-Machine (M2M) communications.

Working Principle

The MIC94080YFT-TR is a monolithic integrated device which features low-power power distribution and load driver control. It\'s integrated with a power transistor that is used to switch and control small blocks of power in order to provide precise control of the power flow. The switch is designed with an under-voltage lockout (UVLO) feature that will not allow the switch to turn on or off until the voltage surpasses the voltage level set. This prevents the MIC94080YFT-TR from drawing excess power and damaging the components. During power voltages, the device can be configured to either load-dump mode or constant-current mode. In load-dump mode, the device will turn off the power to the load once the power voltage falls below a certain level. In constant-current mode, the device will keep the power supplied to the load at a constant level, preventing excessive power supply.

Key Features

The MIC94080YFT-TR offers several key features. These include:

• Integrated low-power Power Distribution Switch and Load Driver
• Wide input voltage range of 2.5V to 18V
• Output current up to 2A
• Under-voltage lockout (UVLO) feature
• Configurable load-dump or current-limit mode
• Maximum quiescent current of 900µA
• Integrated thermal protection
• Space-saving 8-pin MSOP package

The MIC94080YFT-TR is an ideal solution for applications that require precise control of multiple power blocks. Its wide operating voltage range, low power dissipation, and integrated thermal protection make it suitable for a variety of automotive and industrial applications.
