Pin Functions
TYPE ⁽¹⁾
DESCRIPTION
OA
Analog Output drive for overvoltage fault signal, CMOS Output High or
Open Drain Active Low.
P TI recommends connecting the exposed pad to VSS on PCB.
OA
Regulated Supply Output. Requires an external ceramic capacitor for
stability.
IA
Regulated Supply Output Enable. A "high" to enable REG output and
"low" to disable REG output.
IA
Sense input for positive voltage of the lowest cell from the bottom of the
stack.
IA
Sense input for positive voltage of the second cell from the bottom of the
stack.
IA
Sense input for positive voltage of the third cell from the bottom of the
stack.
IA
Sense input for positive voltage of the fourth cell from the bottom of the
stack.
P Power supply input
P
Electrically connected to integrated circuit ground and negative terminal
of the lowest cell in the stack.
(1) IA = Analog input, OA = Analog Output, P = Power connection
