Single-Channel RS-232 Transceiver IC with Auto Power-Down and +-15kV ESD Protection for Serial Communication (TSSOP-16)

The MAX3221EIPWR is a single-channel RS-232 interface IC designed to provide reliable communication between microcontrollers and serial devices using a single 3V to 5.5V supply. It integrates one driver and one receiver, making it ideal for compact embedded systems requiring full RS-232 level translation. The device complies with TIA/EIA-232-F standards and supports data rates up to 250 kbps, ensuring stable data transmission in industrial, computing, and communication applications.

Built with integrated charge pump circuitry, the IC eliminates the need for dual power supplies by generating the required RS-232 voltage levels using only four external capacitors. Advanced power management features such as auto power-down and manual enable control help reduce power consumption in portable and battery-operated systems. With robust IEC 61000-4-2 ESD protection and an INVALID output indicator, the MAX3221EIPWR enhances system reliability and simplifies interface design.

Key Features

  • Single Driver/Receiver Channel: Compact RS-232 solution for point-to-point serial communication
  • Wide Supply Voltage Range: Operates from 3V to 5.5V for compatibility with modern logic levels
  • High Data Rate Support: Handles communication speeds up to 250 kbps
  • Integrated Charge Pump: Generates RS-232 voltage levels using four external capacitors
  • Auto Power-Down Mode: Disables driver and charge pump when not in use to save power
  • Manual Enable Control: Allows external control of driver operation
  • INVALID Output Signal: Indicates disconnected receiver or powered-off remote device
  • Robust ESD Protection: IEC 61000-4-2 compliant protection on RS-232 pins
  • Controlled Slew Rate: 30V/us driver output reduces EMI and ensures signal integrity
  • Compact Package: TSSOP-16 for space-efficient PCB layouts
