MIC2546-2BTS-TR

The MIC2546-2BTS-TR is an integrated power distribution switch specifically designed to power up active components and peripherals of battery powered electronic devices. It is designed to drive low side switches and synchronous rectifiers and serve as the main power distribution switch for the entire power train circuit. Although the MIC2546-2BTS-TR is usually referred to as a power distribution switch, it is actually composed of two major blocks – a MOSFET switch and a voltage regulator. Both components work together to precisely manage the switchover from battery to power supply in order to enable the safe and efficient operation of electronic devices.

The MOSFET switch consists of a N-type and P-type MOSFET transistors on the low side, and a transformer-coupled float driver on the high side. The float driver allows the MOSFET switch to completely shut off any current path between the battery and the load, thus preventing any backflow of current and drastically reducing power waste. The voltage regulator block consists of an external P-type MOSFET, an oscillator and a voltage divider. When the external MOSFET is enabled, the internal oscillator starts, generating a square wave signal which is then sent to the voltage divider. With this arrangement, the voltage regulator ensures that the internal supply voltage is always in a safe range for the components and peripherals of the battery powered electronic device.

The MIC2546-2BTS-TR is a highly versatile power distribution switch and its application fields include, but are not limited to, embedded systems, small appliances, portable electronic devices and even electric vehicles. In fact, due to its high efficiency, reliability, and scalability, the MIC2546-2BTS-TR is widely regarded as the most suitable power distribution switch for automotive applications.

In summary, the MIC2546-2BTS-TR is a highly reliable, efficient and versatile power distribution switch, which makes it an ideal choice for designers of battery powered electronic devices. Thanks to its sophisticated design, the MIC2546-2BTS-TR ensures the safe and efficient operation of all the components and peripherals of the powertrain circuit while drastically reducing the amount of power wasted.
