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.
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. It further includes an 8-bit ADC with 7 multiplexed inputs for voltage and temperature super vision. 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). It 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 36 kB to 64 kB 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.
