Product details

Overview

EVAL-L9963E-MCU from STMicroelectronics is an evaluation board for the L9963E automotive battery monitor IC, enabling development of 48 V battery management systems (BMS) or as a lower-stage node in distributed BMS architectures. It supports up to 14-series Li-ion cell voltage sensing, fully synchronized 16-bit voltage and current measurement, isolated 2.66 Mbps serial communication, onboard SPC574S64E3 MCU with preloaded GUI firmware, and four NTC analog inputs plus PCB temperature sensing.

For engineers reviewing the EVAL-L9963E-MCU datasheet, EVAL-L9963E-MCU pinout, EVAL-L9963E-MCU application, or EVAL-L9963E-MCU equivalent, this board provides full access to all L9963E signals, transformer-isolated SPI interfaces, hot-plug protection, Coulomb counting with pack overcurrent detection in ignition-on/off states, and seamless integration with STSW-L9963E PC GUI software.

Technical Context

The board implements a complete reference design for automotive-grade BMS evaluation, integrating the L9963E battery monitor IC with dual L9963T isolated SPI transceivers, an SPC574S64E3 32-bit Power Architecture MCU, and L9001 multi-rail automotive power supply. All cell voltage, current, and temperature measurements are hardware-synchronized with zero desynchronization delay between samples.

Isolation is achieved via transformer-coupled signaling supporting dual-access ring topology at 2.66 Mbps, while the onboard microcontroller runs GUI firmware that communicates with STSW-L9963E PC software via FTDI-based USB virtual COM port and JTAG debug interface.

FAQ

What software is required to operate EVAL-L9963E-MCU?

The board requires STSW-L9963E PC GUI software, which provides real-time visualization of cell voltages, current, temperatures, fault status, and Coulomb counting data. Firmware is preloaded on the onboard SPC574S64E3 MCU; no additional programming is needed for basic operation. The GUI connects via USB virtual COM port using standard Windows drivers.

Can EVAL-L9963E-MCU be used standalone without a host PC?

Yes - the onboard SPC574S64E3 MCU runs autonomous firmware that manages L9963E configuration, data acquisition, and local diagnostics. While GUI interaction requires a PC, the board can log data internally or communicate over isolated SPI to a master BMS controller without continuous host connection.

Does the board support hot-plug insertion into live battery packs?

Yes - it integrates a dedicated hot-plug protection circuit using STL8N10LF3 MOSFET and current-limiting resistors, enabling safe connection/disconnection to powered battery strings without damaging the L9963E or corrupting measurements.

How does EVAL-L9963E-MCU interface with other BMS stages?

It uses two L9963T isolated SPI transceivers to form a dual-ring communication backbone, supporting up to 16 nodes. Each transceiver provides 2.66 Mbps transformer-isolated SPI links, allowing daisy-chained or redundant ring topologies with automatic failover - essential for distributed high-voltage BMS scalability.
