Overview
The MAX3232EIPWRQ1 is an automotive-grade RS-232 transceiver manufactured by Texas Instruments. It integrates two line drivers, two line receivers, and a dual charge-pump circuit within a 16-pin TSSOP package. The device operates from a single 3V to 5.5V supply voltage and supports data signaling rates up to 250kbit/s. It provides ±15kV IEC ESD protection on serial-port connection pins, including ground. The typical standby current is 300μA, and it requires four external capacitors for operation.
Feature Summary
- Automotive qualification compliant with AEC-Q100 standards
- Integrated dual charge pump requiring only four small external capacitors
- Robust electrostatic discharge protection rated at ±15kV IEC on all serial port pins
Applications
- Industrial PCs
- Wired networking equipment
- Data center and enterprise computing systems
- Battery-powered portable devices
Procurement Notes
Verify the specific ordering suffix against the latest TI Package Option Addendum to confirm material type, lead finish, and moisture sensitivity level. Ensure the component status remains Active Production before finalizing procurement plans. Cross-reference the part marking code MB3232I with incoming inspection requirements to validate authenticity and traceability during quality control processes.
Selection Notes
Select this component when automotive reliability and high ESD immunity are required for RS-232 interfaces. It serves as a direct pin-compatible replacement for standard catalog versions like the MAX3232E. Consider the SNx5C3232 series if higher data rates up to 1Mbit/s are necessary while maintaining the same physical footprint and pinout configuration.
Part Context
This device belongs to the MAX3232E-Q1 family of multichannel RS-232 line drivers and receivers. It shares the core electrical architecture with the commercial MAX3232E but undergoes stricter manufacturing controls to meet automotive industry standards. The Q1 designation specifically indicates its qualification for use in demanding vehicular electronic environments.
