Microchip Technology's MIC5841YV: An Efficient 8-Bit Serial-Input Latched Driver

The MIC5841YV from Microchip Technology is a robust integrated circuit designed to provide a convenient interface between microprocessors and individual peripheral devices that require high-voltage and high-current driving capabilities. This 8-bit serial-input latched driver is particularly suitable for driving lamps, relays, or printer hammers in a microprocessor-controlled system where the output requirements surpass the capability of the microprocessor's I/O ports.

With a built-in CMOS shift register and latches, the MIC5841YV allows direct interfacing with microprocessor buses, effectively reducing the number of required I/O lines. This feature is particularly beneficial in applications where PCB space is at a premium, and a reduction in the number of components can lead to a more compact and cost-effective design.

The device operates on a 5V logic supply while being capable of withstanding output voltages up to 50V, and it can deliver continuous output currents up to 500mA to each of its eight output drivers. This high level of performance ensures that the MIC5841YV can handle a wide range of high-power devices, making it a versatile choice for various applications.

The outputs are equipped with integral suppression diodes that provide protection against inductive transients, making the MIC5841YV an excellent choice for driving inductive loads such as relays and solenoids. This protective feature enhances the reliability and longevity of both the driver and the peripheral devices it controls.

The MIC5841YV is available in a 22-lead plastic dip package and is specified for operation over the temperature range of -40°C to +85°C. Its robust design and wide operating temperature range make it suitable for use in challenging environments and for applications that demand consistent performance under varying conditions.

In summary, the MIC5841YV from Microchip Technology is a high-voltage, high-current driver that offers an efficient solution for expanding the output capabilities of microprocessor systems. Its built-in protection, high integration, and ease of interfacing make it an ideal choice for designers looking to streamline their high-power driving applications.
