Infineon Technologies TLE984x Motor/Relay Driver ICs

Infineon TLE984x Motor/Relay Driver IC 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.

Its peripheral set includes a 10-bit ADC with 13 multiplexed analog inputs to process up to 5 high-voltage monitoring inputs, 6 low-voltage inputs, and 2 high-voltage inputs for sensing the battery voltage and the supply of the device. TLE984x further includes an 8-Bit ADC with 7 multiplexed inputs for voltage and temperature supervision. Its digital peripherals include a PWM signal generator unit and 16-bit timers along with a number of general-purpose I/Os (Serial Interfaces and UARTs). TLE984x includes an on-chip linear voltage regulator to supply external loads.

The TLE984x family concept offers scalability in terms of Flash memory sizes ranging from 36kB to 64kB with pin-compatible devices. It is specifically designed to drive a wide range of LIN-slave motor control automotive applications via a relay or via a PN MOSFET Half-Bridge, such as window lifts, sunroofs, wipers, electric fans and pumps to name a few.
