The MIC94071YMT-TR is an integrated circuit produced by Micrel and part of their higher density SPI port-controlled power-distribution switch (PD power) portfolio. This device is designed to control several power distribution switches, load drivers and other components in a variety of applications. It has a small footprint, high power efficiency and low power-consuming feature.

The MIC94071YMT-TR is particularly suited for applications where high current levels or high in-rush occur, such as in-vehicle LED lighting and LED display systems, where large voltages and currents can cause interference with other components. This device is also well-suited for rugged and remote environments, such as avionics, industrial, automotive, and military applications, due to its low power requirements, high integration, and the ability to remain operational even in extreme temperatures.

The MIC94071YMT-TR has a wide range of features that are beneficial for both power and output switching. The device can handle up to 8 channels of switches and/or load controllers and handle IN/ OUT/ HB pin control and/or logic-level - controlled outputs. Each output can also be configured as a share or slave, allowing the device to switch or control multiple channels or logic signals at the same time.

The MIC94071YMT-TR also contains various protection mechanisms to protect the power sources, such as reverse-polarity protection, over-voltage protection, under-voltage protection, overcurrent protection, over-temperature protection, and reverse-discharge protection. This device is also equipped with ESD protection and an internal thermal shutdown feature that automatically turns off any output or channel when the temperature rises beyond a certain level. An optional operating temperature range of -40c to 85c is also available.

The MIC94071YMT-TR features a variety of digital and analog output structures. Digital outputs are implemented with open-collector, push-pull and latch-up outputs, and the analog outputs can be either single-ended or differential. The device also supports a wide range of operating voltages from 3.3v to 24v, as well as logic levels from 1.8v to 5v.

The MIC94071YMT-TR also includes a configurable sequencer that can be used to sequence the on/off switching of the power supplies and the outputs, as well as the current channel availability. Additionally, the device contains independent low-bias, high-speed pulse-width modulation outputs and isolators to improve the accuracy and control of the outputs, and to reduce the number of drivers and their size. This, combined with its integrated isolation and ground-referenced input, allows for effective isolation between different power and logic domains.

The MIC94071YMT-TR also contains a number of power-saving modes to optimize power consumption. These include a power-down mode that turns off the device when it is not being used, as well as a low power-mode that switches off unused channels and lowers the current — reducing power consumption. In addition, the device can be configured to auto-restart after an unexpected power interruption, preventing it from ever shutting down completely.

The MIC94071YMT-TR is an ideal solution for applications where power control is needed, such as in-vehicle LED lighting, industrial automation, communications, and automotive systems. Its efficient power consumption and high integration level, combined with its various protection mechanisms, make it suitable for even the most extreme environments. With its wide operating temperature range and a variety of digital and analog output options, it is an effective and reliable choice for any power control application.
