MUTE

Mute status (read on-

ly)

1: mute is activated and discharging is disabled

0: mute is deactivated

FDRF

Force digital redun-

dancy failure

1: forces the digital redundancy comparison for ADC conversions to fail

0: enables the normal redundancy comparison

PS,

Bits[1:0]

Digital redundancy

path selection

11: redundancy is applied only to the ADC3 digital path

10: redundancy is applied only to the ADC2 digital path

01: redundancy is applied only to the ADC1 digital path

00: redundancy is applied sequentially to the ADC1, ADC2, and ADC3 digital paths during cell conversions and applied to ADC1 during

AUX and STATUS conversions

DTMEN

Enable discharge tim-

er monitor

1: enables the discharge timer monitor function if the DTEN pin is asserted

0: disables the discharge timer monitor function. The normal discharge timer function is enabled if the DTEN pin is asserted

CxV

Cell x voltage1

x = 1 to 18

16-bit ADC measurement value for Cell x

Cell voltage for Cell x = CxV × 100 μV

CxV is rest to 0xFFFF on power-up and after clear command

GxV

GPIO x voltage1

x = 1 to 9

16-bit ADC measurement value for GPIOx

Voltage for GPIOx = GxV × 100 μV

GxV is reset to 0xFFFF on power-up and after clear command

REF

2nd reference volt-

age1

16-bit ADC measurement value for 2nd reference

Sum of all cells meas-

urement1

16-bit ADC measurement value of the sum of all cell voltages, sum of all cells voltage = SC × 100 μV × 30

ITMP

Internal die tempera-

ture1

16-bit ADC measurement value of the internal die temperature, temperature measurement voltage = ITMP × 100 μV/7.6mV/°C − 276°C

Analog power supply

voltage1

16-bit ADC measurement value of the analog power supply voltage, analog power supply voltage = VA × 100 μV, the value of VA is set by

external components that must be in the range of 4.5 V to 5.5 V for normal operation

Digital power supply

voltage1

16-bit ADC measurement value of the digital power supply voltage, digital power supply voltage = VD × μV, normal range is within 2.7 V

to 3.6 V

CxOV

Cell x overvoltage flag x = 1 to 18

Cell voltage compared to VOV comparison voltage

0: Cell x not flagged for overvoltage condition

1: Cell x flagged

CxUV

Cell x undervoltage

flag

x = 1 to 18

Cell voltage compared to VUV comparison voltage

0: Cell x not flagged for overvoltage condition

1: Cell x flagged
