Abstract

A MUX (72) for a battery management system (10') includes a first input terminal for coupling to a first pin (C<i>) of a battery stack (B), a second input terminal for coupling to a second pin (C<i-1>) of the battery stack (B), and a third input terminal for coupling to a third pin (C<i-2>) of the battery stack (B). A first switch (SW<i>) has a respective first terminal (100<i>) coupled to the first input terminal of the MUX, a second switch (SW<i-1>) has a respective first terminal (100<i-1>) coupled to the second input terminal of the MUX, and a third switch (SW<i-2>) has a respective first terminal (100<i-2>) coupled to the third input terminal of the MUX. An AFE and selection circuit (724) includes a first input terminal coupled to a second terminal (102<i>) of the first switch (SW<i>), a second input terminal coupled to a second terminal (102<i-1>) of the second switch (SW<i-1>), a third input terminal coupled to a second terminal (102<i-2>) of the third switch (SW<i-2>), a first output terminal for coupling to a positive input of a first level shifter circuit (16<i>), a second output terminal for coupling to a negative input of the first level shifter circuit (16<i>), a third output terminal for coupling to a positive input of a second level shifter circuit (16<i-1>), and a fourth output terminal for coupling to a negative input of the second level shifter circuit (16<i-1>). Each of the first, second, third and fourth output terminals of the AFE and selection circuit (724) is selectively couplable to any of the first, second and third input terminals of the AFE and selection circuit (724).
