Infineon Technologies Embedded Power TLE9877 / 79

With the extension of the successful TLE987x family, Infineon is launching 2 new variants with a brand-new TQFP package. The new variants, TLE9877QTW40 and TLE9879QTW40, are highly integrated automotive-qualified devices enabling cost and space-efficient solutions for mechatronic BLDC motor drive applications such as pumps and fans.

Key features

• 32-bit Arm® Cortex®-M3 core, up to 40 MHz clock frequency
• MOSFET driver including charge pump
• 1 LIN 2.2 transceiver
• High-speed operational amplifier for motor current sensing via shunt

Additional features

• On-chip OSC and PLL for clock generation
  • PLL loss-of-lock detection
• Single power supply from 5.5 V to 27 V
• Temperature range Tj = -40°C to +175°C
• 6 KB RAM
• TLE9877QTW40: 64 KB flash
• TLE9879QTW40: 128 KB flash
• Package:
  • TQFP-48
  • RoHS compliant "Green" package
  • AEC-qualified

Applications

• BLDC motor drive applications
• e.g. pumps
• e.g fans

Additional Info

• Enables cost and board space improvements:
  • The TLE987x family allows driving MOSFETs at VBATT ≥ 6 V with a low number of external components, providing a very cost-effective solution on a system level.
  • A minimum number of external components required reduces the overall BOM cost further.
• Enables 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 the same design:
  • Some TLE987x 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.
