tle9842-2qx 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.

tle984x系列评估板
the tle984x evaluation board offers complete evaluation of all functions and peripherals of the tle984x product family.this board is designed to provide a fast and easy start of evaluation, for infineons embedded power tle984xdevice family. initialy, the evaluation board brings several interfaces and interconnections.
the tle984x device is placed in the center of the pcb. a socket provides the possibility to test and evaluate all icsout of the tle984x device family. every pin of the ic is connectable via rows of pinheader. the board is protectedagainst reverse polarity of input voltage supply. a bidirectional relay can be connected to the integrated lowsideswitches, optionaly. in addition to that, a scew-connector is placed near the relay to contact and drive a dcmotor(example: window lift motor).
the evaluationboard provides an on board debugger. it provides a swddebugconnection and a virtual com port for serial uart communication.highside and lowside switches and vddext are connectable via 4mm standard laboratory wires.
the high-voltage-monitor pins can be triggered with dedicated pushbuttons.for analog input values a potentiometer is connected to pin p2.2.the lin connection is able to be configured to master and slave mode.
