Infineon Technologies TLE986x/7x embedded power

Infineon is extending the TLE986x/7x families with the launch of 4 new variants with 256 KB flash and additional package. New variants provide a performance- and cost-optimized solution for automotive BDC/BLDC applications such as wiper. 

This portfolio extension addresses the increased need for flash, driven by European car OEMs requiring 30% of free flash at the time the application has SOP and the need for additional flash coming from software-over-the-air (or in the field) updates.

Key features

• 32-bit Arm^® Cortex^®-M3 core
• 256 KB flash
• 8 KB RAM
• On-chip OSC and PLL for clock generation

Additional features

• MOSFET driver including charge pump
• 1 LIN 2.2 transceiver
• High-speed operational amplifier for motor current sensing via shunt
• Single power supply from 5.5 V to 27 V
• TLE9872-2QXA40 has two differential 14-bit sigma-delta ADCs
• Green package (RoHS compliant)
• AEC-qualified

 Benefits:

• Enable cost and board space improvements - minimum number of external components reduces BOM cost.
• The TLE986x/7x families allow driving MOSFETs at VBATT ≥ 6V with a low number of external components, providing a very cost effective solution on a system level. 
• Enable high levels of system reliability
• Extensive diagnostics and protections are embedded within the System-on-Chip, more than a discrete approach can offer.
• Support in-cabin and underhood applications with same design
• some TLE986x/7x derivatives are available for different temperature ranges (Grade-0 and Grade-1) in different packages to give the customer maximum flexibility while being software and pin compatible.

Applications

• Automotive BDC/BLDC applications
