Transceiver enables robust nodes in LIN bus systems
1 min read
NXP Semiconductors has unveiled a new LIN transceiver series featuring an integrated low drop voltage regulator in a small 3 x 3mm leadless package.
The TJA1028 voltage regulator is designed to power an automotive electronic control unit (ECU) and integrates the major peripheral functions around the microcontroller of a typical LIN networked ECU into a single chip. According to the mixed signal specialist, the combination of voltage regulator and bus transceiver makes it possible to develop compact yet powerful slave nodes in LIN bus systems.
NXP says the TJA1028 has been optimised to handle low speed data communication in vehicles and for LIN slave applications such as rain light sensors, mirror modules, window lifters and switch panels. Designed specifically to meet the requirements of vehicle OEMs, it is said to feature strong electrostatic discharge and electromagnetic compatibility performance with bus output designed to withstand high voltages.
Available in 3.3 and 5.0V variants. the range is optimised to deliver up to 70Ma. In order to minimise current consumption, it supports a sleep mode and a low power standby mode, in which the LIN transceiver is switched off while the voltage regulator is still supplying the microcontroller.
