The MIC5800YN is part of a series of Power Management Integrated Circuits (PMIC), which are specifically designed for Power Distribution Switches and Load Drivers. The MIC5800YN is a low voltage, low current high performance IC which utilizes a DMOS output transistor and a series of step up/down converters to drive and control power distribution systems. It features a wide input voltage range (2.7V–60V), a high switching speed, and a high efficiency range (up to 95%).

The MIC5800YN provides the user with two independent outputs, one regulated and one non-regulated. The regulated output is designed to be capable of providing up to 3A with a minimum load range of 30mA, while the non-regulated output can provide up to 6A. Both outputs feature a low quiescent current, fast response time and a wide temperature range.

The MIC5800YN has built in protection features such as over current, over voltage, and reverse current protection. It is also designed to reduce the output noise which can be generated from the power supply loading. The low input and output capacitors used by this PMIC, along with its wide temperature range, ensures minimal power loss. The MIC5800YN is also optimized for Constant Current Control, allowing for more efficient power delivery.

The working principle of the MIC5800YN is relatively straightforward. The device utilizes its two independent outputs, providing a regulated and non-regulated output. The regulated output is designed to utilize a DMOS output transistor and a series of step up/down converters to reduce the output voltage and current of the power supply. This regulated output can then be utilized to drive the low voltage, low current high performance devices. The non-regulated output utilizes the same DMOS transistor as the regulated output, but its output voltage and current are not regulated. Instead, the non-regulated output provides high pulse power for devices that require high peak power delivery, such as motors and solenoids.

In summary, the MIC5800YN is a low voltage, low current high performance IC with two independent outputs. The regulated output is designed to reduce the output voltage and current of the power supply while the non-regulated output provides high peak power delivery. It features a wide input voltage range, a high switching speed, and a high efficiency range. It also features built in protection features such as over current, over voltage, and reverse current protection. Finally, it is optimized for Constant Current Control, allowing for more efficient power delivery. Overall, the MIC5800YN is an excellent choice for power distribution and load driver applications.
