Working Principles

The MAX202ID is based on a charge pump voltage converter that generates positive and negative voltages required for RS-232 communication. It uses a combination of capacitors and switches to convert the 5V supply voltage into higher voltages needed for RS-232 signaling. The transceiver then converts the logic-level signals to RS-232 voltage levels for transmission and vice versa for reception.

Detailed Application Field Plans

The MAX202ID is commonly used in various applications, including:

1. Industrial automation systems
2. Point-of-sale terminals
3. Networking equipment
4. Medical devices
5. Consumer electronics
