Maxim Integrated MAX3226ECAE: 3.0V to 5.5V, 1µA, 250kbps, RS-232 Transceivers with AutoShutdown Plus™

The MAX3226ECAE from Maxim Integrated is a highly efficient RS-232 transceiver tailored for battery-powered applications due to its low-power consumption and enhanced power-saving features. This integrated circuit is part of a family of transceivers designed to operate at a supply voltage range of 3.0V to 5.5V, making it versatile for various applications including portable or compact devices.

With a quiescent current of just 1µA and a transmission rate of up to 250kbps, this transceiver is an optimal solution for applications that require a balance between power efficiency and data rate performance. The MAX3226ECAE features Maxim's proprietary AutoShutdown Plus™ technology, which significantly reduces power consumption by entering a low-power shutdown mode when the RS-232 cable is disconnected, or the connected peripherals are turned off. This feature greatly extends the battery life of the end application.

The device is equipped with two drivers and two receivers, offering a reliable serial communication interface for transmitting and receiving data. It also includes a 0.1µF charge pump capacitor which minimizes the required external components, saving space on the PCB and reducing overall design complexity.

The MAX3226ECAE comes in a 16-pin SSOP (Shrink Small Outline Package) that provides a compact footprint suitable for space-constrained applications. Its ESD protection exceeds ±15kV using the Human Body Model, ensuring robust performance in environments prone to electrostatic discharge.

Key features of the MAX3226ECAE include:

• Supply voltage range: 3.0V to 5.5V
• Low quiescent current: 1µA
• Data rate: 250kbps
• AutoShutdown Plus™ technology for enhanced power saving
• Integrated charge pump circuitry with small 0.1µF capacitors
• ESD protection: ±15kV Human Body Model
• 16-pin SSOP package for compact designs

The MAX3226ECAE is ideal for portable instruments, PDAs, notebooks, and other battery-powered devices where efficient power management and reliable data transmission are crucial. Maxim Integrated's commitment to quality and performance makes this transceiver a top choice for designers looking to enhance their serial communication capabilities while maintaining low power consumption.
