The DMN2008LFU-13 is a transistor array integrated circuit (IC) produced by Motorola that has numerous applications in the embedded personal computing and communications industry. It is a multifunction P-channel MOSFET array consisting of two MOSFETs in a two-row leaded package and designed to provide the advantages of low on-resistance and fast switching for high current applications. Originally released in 1989, the DMN2008LFU-13 retains its popularity today due to its rock-solid reliability and high-performance capabilities.

The DMN2008LFU-13 is designed to provide a fast switching, low output impedance for high current applications. The MOSFETS in the array provide low on-resistance, enabling it to be used for high-speed switching and low-voltage analog signal switching. The device is also suitable for driving power MOSFET switches and providing continuous current up to 87A.

The DMN2008LFU-13 is based on the Darlington pair configuration to provide extremely low on-resistance and fast switching. This architecture allows the device to switch up to twice as fast as a standard SINGLE P-channel MOSFET array and make it suitable for power supply applications, as well as providing high output current control in light load conditions.

In terms of performance, the DMN2008LFU-13 has a maximum drain source voltage of 35 V, a total gate charge of 18 nC and a total gate-source capacitance of 5 pF. It has a low on-resistance of 250 mΩ and a gate-source voltage of 5V. The device also has excellent surge current handling capabilities and is capable of handling peak currents up to 8A.

Due to its maximum drain source voltage, fast switching capabilities, and low-resistance characteristics, the DMN2008LFU-13 is particularly suitable for switch-mode power supplies, buck converters, and other DC-DC converters. This is because the device can provide a fast, tight response for challenging load requirements. For example, the device is particularly useful for driving secondary MOSFET switches in systems with output power levels of 10W or more.

The DMN2008LFU-13 is also suitable for a variety of other applications, including automotive, industrial, and consumer electronics. It can provide power and control for applications such as motor drivers, battery management systems, and communications equipment. In particular, it can be used to drive complex switching patterns in motor drivers for industrial and healthcare applications.

The DMN2008LFU-13 is available in two packages: the two-row leaded package (SOIC) and the J-lead DFN package. The two packages offer a wide range of design options, including package size, mounting, and power handling capabilities. This provides flexibility when designing unique applications.

The bottom line is that the DMN2008LFU-13 is an excellent choice when it comes to ensuring high-performance, reliable switching in embedded personal computing and communications applications. Its fast switching, low-resistance characteristics, and excellent surge current handling capabilities make it particularly suitable for switch-mode power supplies, buck converters, and many other DC-DC converters. Its availability in two different packages additionally provides plenty of design flexibility.
