Relay Driver IC with µC Description

TLE9842QX is a part of the TLE984x product family. The TLE984x product family integrates an ARM® Cortex® M0 microcontroller core along with relay drivers, high side switches, LIN transceiver and a power supply system that enables the device to operate at the vehicle battery level. The TLE984x family offers scalability in terms of Flash memory sizes ranging from 36kB to 64kB with pin-compatible devices. The TLE984x family was specifically designed to fit to a wide range of LIN-slave applications where a small package form factor and a minimum number of external components are essential. The TLE984x product family is offered in a leadless VQFN-48 package to save board space.
