Strengthening the link between the real and the digital worldTLE9015QU
Overview
The TLE9015QU belongs to Infineon´s Battery Management Tranceiver IC product family
The TLE9015QU is a battery monitoring transceiver IC designed for connecting several TLE9012AQU devices in a daisy chain inside a Li-Ion battery. By means of its two UART and iso UART interface pairs it can support ring communication improving the availability of the system by a low cost.
It also enables bidirectional information flow by including an error management unit including several inputs and outputs that are programmable on each TLE9012AQU.
Summary of Features
- Two UART ports for serial communication to host microcontroller
- Two iso UART ports for daisy chain communication inside battery pack
- Fully transparent communication scheme from µC to sensing IC
- Ring mode topology compatible (only 1 device needed)
- CRC check for communication integrity (no CRC modification)
- High robustness against external noise
- General purpose error pin
- Two external fault inputs with internal latching
- Error output pin to trigger external microcontroller
- Internal supply monitoring
- Low energy sleep mode
- AEC-Q100 qualified
Benefits
- Robust communication without need of transformers or common mode chokes
- Master-on-Top or Master-on-bottom selectable without tedious configuration
- Bi-directional communication scheme using error management logic
- Ring mode topology for further system availability at low cost
