New Product Introduction

NPI Body

Infineon Technologies Embedded Power TLE9877 / 79

TLE9877QTW40 and TLE9879QTW40 3-phase bridge driver IC with integrated Arm® Cortex® M3

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.

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.

Available tools

TLE987X EVALB_TQFP

The TLE987X EVALB_TQFP offers complete evaluation of all functions and peripherals of the TLE987x product family and allows direct connection to a BLDC motor via MOSFETS in B6-Bridge configuration, it includes: B6-Bridge for BLDC motor drive, UART and LIN for communication, direct access to all device I/Os and an onboard debugger.
