The device eliminates the need for a separate 5V supply rail that traditional 5V CAN transceivers require, simplifying system design and reducing BOM cost. The transceiver is compliant with the ISO 11898 standard and supports data rates up to 1Mbps. Three operating modes are selectable via the RS pin: high-speed mode (RS connected to GND) for maximum data rate, slope control mode (RS connected through a resistor to GND) for reduced EMI at lower data rates, and standby mode (RS connected to VCC) with 370nA ultra-low current consumption. The reference voltage output (Vref pin) provides a stable 0.5VCC voltage for CAN bus biasing or comparator applications. The differential transmitter and receiver provide reliable communication with common-mode input voltage range of -8V to +14V. The 370nA standby current enables use in battery-powered CAN sensor nodes that spend most of their time in sleep mode.","working_principle":"The SN65HVD230DR converts between the MCU's digital CAN signals and the differential bus signals at 3.3V supply. (1) Transmit: When the MCU drives TXD low (dominant), the transceiver drives CANH high and CANL low, creating a differential voltage on the bus. When TXD is high (recessive), both CANH and CANL are biased to approximately VCC\/2 (1.65V). The 3.3V supply directly powers the bus driver, eliminating the 5V requirement. (2) Receive: The differential receiver monitors the CANH-CANL voltage. When the differential exceeds the threshold, RXD is driven low (dominant). (3) Slope Control: In slope control mode, the RS resistor limits the output slew rate, reducing high-frequency signal content that causes EMI. This allows operation at lower data rates (up to 125kbps) with improved EMC performance without external filters. (4) Standby: In standby mode, the transmitter is disabled and the receiver operates in low-power mode with 370nA current, monitoring the bus for dominant wake-up frames.","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Type<\/th><th>Function<\/th><\/tr><tr><td>1<\/td><td>D<\/td><td>Input<\/td><td>Transmit data input<\/td><\/tr><tr><td>2<\/td><td>GND<\/td><td>Ground<\/td><td>Ground<\/td><\/tr><tr><td>3<\/td><td>VCC<\/td><td>Power<\/td><td>3.3V supply<\/td><\/tr><tr><td>4<\/td><td>R<\/td><td>Output<\/td><td>Receive data output<\/td><\/tr><tr><td>5<\/td><td>Vref<\/td><td>Output<\/td><td>Reference voltage (VCC\/2)<\/td><\/tr><tr><td>6<\/td><td>CANL<\/td><td>I\/O<\/td><td>CAN bus low<\/td><\/tr><tr><td>7<\/td><td>CANH<\/td><td>I\/O<\/td><td>CAN bus high<\/td><\/tr><tr><td>8<\/td><td>RS<\/td><td>Input<\/td><td>Mode select (high-speed\/slope\/standby)<\/td><\/tr><\/table>","application_scenarios":"<ul><li>3.3V MCU-based CAN bus systems without 5V supply rail<\/li><li>Industrial automation and process control with slope control mode<\/li><li>Medical device CAN networks with 370nA standby current<\/li><li>Battery-powered CAN sensor nodes with ultra-low standby power<\/li><\/ul>","alternative_models":"<table><tr><th>Manufacturer<\/th><th>Part Number<\/th><th>Package<\/th><th>Notes<\/th><\/tr><tr><td>TI<\/td><td>SN65HVD231DR<\/td><td>SOIC-8<\/td><td>Loopback feature for diagnostics<\/td><\/tr><tr><td>TI<\/td><td>SN65HVD233DR<\/td><td>SOIC-8<\/td><td>3.3V CAN with diagnostic loopback<\/td><\/tr><tr><td>NXP<\/td><td>TJA1040T<\/td><td>SOIC-8<\/td><td>5V, improved EMC<\/td><\/tr><tr><td>Microchip<\/td><td>MCP2561-E\/SN<\/td><td>SOIC-8<\/td><td>CAN FD, 5V, MCP2551 upgrade<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/ic-vendor.com\/zh\/wp-json\/wp\/v2\/posts\/7222","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/ic-vendor.com\/zh\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/ic-vendor.com\/zh\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/ic-vendor.com\/zh\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/ic-vendor.com\/zh\/wp-json\/wp\/v2\/comments?post=7222"}],"version-history":[{"count":0,"href":"https:\/\/ic-vendor.com\/zh\/wp-json\/wp\/v2\/posts\/7222\/revisions"}],"wp:attachment":[{"href":"https:\/\/ic-vendor.com\/zh\/wp-json\/wp\/v2\/media?parent=7222"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/ic-vendor.com\/zh\/wp-json\/wp\/v2\/categories?post=7222"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/ic-vendor.com\/zh\/wp-json\/wp\/v2\/tags?post=7222"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/ic-vendor.com\/zh\/wp-json\/wp\/v2\/chip_brand?post=7222"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
