Infineon – TLE9015QU—Battery management transceiver IC
The TLE9015QU is a general-purpose transceiver IC to be used in multi-cell battery systems to enable the communication between the main host microcontroller and the slaves in the battery.
The TLE9015QU enables communication by 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 ensuring a cost optimized robust system solution. It also enables bidirectional information flow by including an error management unit including several inputs and outputs that are programmable on each TLE9012AQU.
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
Benefits:
- Robust communication without need of transformers or com-mon mode chokes
- Master-on-top or master-on-bottom selectable without tedious configuration
- Bi-directional communication scheme using error management logic
- Ring mode topology ensuring a cost optimized robust system solution
Applications:
- Hybrid Electric Vehicle (HEV)
- Plug-in Hybrid Electric Vehicle (PHEV)
- Battery Electric Vehicle (BEV)
- Energy Storage System (ESS)
- Home Energy Storage System (HESS)
- Commercial, Construction and Agricultural Vehicles (CAV), oth-er small vehicles (e.g. eScooter, eBike, etc.)
