TJA1052i isolated CAN high-speed CAN transceiver CAN HS-CAN transceiver with integrated galvanic isolation The TJA1052i is a high-speed controller area network (HS-CAN) transceiver that provides a galvanically isolated interface between an HS-CAN protocol controller and the physical two-wire CAN bus. It is specifically aimed at (hybrid) electric vehicles ((H)EVs), where galvanic isolation is necessary to bridge between the high and low voltage levels. Key features ` Protect electronics from overvoltage, ground offset and ` 5 kV (RMS) rated isolation voltage, compliant with UL1577, reverse current IEC61010 and IEC60950 ` Signal integrity; improved noise immunity ` Suitable for 12 V and 24 V systems; compatible with 3 V to 5 V microcontrollers Applications ` Low electromagnetic emission (EME) and high EMI ` Battery management systems ` Supports ISO6469 ‘Electrically propelled road vehicles. ` Chargers Safety specifications.’ ` Inverters ` Bus pins protected against transients in automotive ` DC/DC converters environments ` Other ECUs operated from the high voltage domain ` Transmit Data (TxD) dominant time-out function ` Undervoltage detection on supply pins As a member of our third generation HS-CAN transceivers, the TJA1052i offers significant advantages over previous Key benefits
