ST EVAL-L9963E-MCU User manual

Introduction
The EVAL-L9963E-MCU is a hardware tool for evaluation and development and is ideal for rapid prototyping of a 48 V battery
management system (BMS) or as lower stage of a distributed BMS. This board can be used to evaluate the features of the
L9963E device and L9963T.
The EVAL-L9963E allows the user to connect up to 14 channels for cell voltage sensing, one channel for current sensing, and
up to 4 channels for temperature sensing (plus an additional on-board NTC to sense PCB temperature). The board provides an
onboard microcontroller with preloaded firmware intended to be used with STSW-L9963E GUI (graphical user interface).

2.3 Hot plug protection
Figure 5. Hot plug protection circuit
The structure shown in the Figure 5 on the GND path will help withstanding the hot plug by limiting the inrush
current incoming from any L9963E pin connected to the centralized clamp.
Working principle is the following:
When L9963E is OFF and no cell is connected, the VTREG regulator is shut down and MHOT is safely kept off by
the RPD pull down resistor.
Upon the first hot plug event, inrush current incoming from the centralized clamp is forced to flow into RHOT
resistor, which offers proper limiting.
Any VDS voltage spike on MOSFET during hot plug could be coupled to the gate via the parasitic Miller
capacitance. Unwanted turn-on is safely filtered by CGS, that helps keeping VGS below the threshold voltage.
Hence the MOSFET will stay OFF during hot plug.
If the hot plug voltage is enough to guarantee L9963E powerup the MOSFET will be turned on by VTREG
regulator with a proper delay, obtained through RG gate resistor.
Finally, during L9963E normal operation the MOSFET will be ON, thus guaranteeing a very low impedance path
(few mΩ) on the analog GND (GND_B) line.
Such a small shift between L9963E GND and battery pack GND will not alter cell measurement at all, since cell
ADCs are fully differential. Hence, both cell and sum of cells measurements will be accurate.
Moreover, since L9963E only drains few mA from the battery pack, error introduced on the VBAT stack
measurement via internal voltage divider will be negligible.
Also the CSA used for Coulomb counting features a fully differential architecture, thus being immune to such a
small common mode shift.
