MAX3232EIPWRQ1 General Description

The MAX3232EIPWRQ1 is a high-speed, low-power RS-232 transceiver IC designed for automotive applications. It operates over a wide supply voltage range of 3.0V to 5.5V and features a shutdown mode to conserve power. This IC includes two transmitters and two receivers, offering full-duplex communication capability. It is compliant with the ESD protection standard of ±15kV for air and ±8kV for contact discharge.With its integrated charge pump, the MAX3232EIPWRQ1 generates the necessary RS-232 voltage levels from a single +3.0V to +5.5V supply, eliminating the need for external components. This transceiver is specified for operation over the extended temperature range of -40°C to +125°C, making it suitable for harsh automotive environments.The MAX3232EIPWRQ1 comes in a space-saving 16-pin TSSOP package, making it ideal for applications with limited board space. Its automotive qualification ensures reliability and performance in automotive systems such as engine control modules, body control modules, and infotainment systems
