Infineon Technologies TLE9015DQU iso UART Transceiver IC
Infineon Technologies TLE9015DQU iso UART Transceiver IC is intended for connecting several TLE9012DQU devices in a daisy chain inside a Li-Ion battery. The device's two UART and iso UART interface pairs allow support ring communication and improve the system's availability at a low cost. The Infineon TLE9015DQU IC enables bidirectional information flow by including an error management unit including several inputs and outputs that are programmable on each TLE9012DQU.
Features
- Compatibility for ring mode topology
- Two UART ports for serial communication to host microcontroller
- Two iso UART interfaces for communication to other BMS ICs
- 2Mbit/s data rate for fast communication
- Fully transparent communication scheme from UART to iso UART
- Integrated internal logic for minimizing pin count on the UART side
- Differential current edge-triggered iso UART communication interface
- High robustness against external noise
- Two external fault inputs (EMM and ERRQ_ext)
- Latching error output pin for triggering external microcontroller
- Internal supply monitoring
- Green Product (RoHS compliant)
Applications
- Hybrid Electric Vehicle (HEV)
- Plug-in Hybrid Electric Vehicle (PHEV)
- Battery Electric Vehicle (BEV)
