Description

VIN6 to VIN0
Analog Input 6 to Analog Input 0. VIN0 should be connected to the base of the series-connected battery cells.
VIN1 should be connected to the top of Cell 1, VIN2 should be connected to the top of Cell 2, and so on (see
Figure 28 and Figure 29).
2, 4, 6, 8,
10, 12
CB6 to CB1
Cell Balance Output 6 to Cell Balance Output 1. These pins provide a voltage output that can be used to supply
the gate drive of an external cell balancing transistor. Each CBx output provides a 0 V or 5 V voltage output
referenced to the absolute amplitude of the negative terminal of the battery cell that is being balanced.
14
MASTER
Voltage Input. Connect the MASTER pin of the AD7280A that is connected directly to the DSP/microprocessor
to the VDD supply pin through a 10 kΩ resistor. In an application with two or more AD7280As in a daisy chain,
the MASTER pins of the remaining AD7280As in the daisy chain should be tied to their respective VSS supply
pins through 10 kΩ resistors.
15
PD
Power-Down Input. This input is used to power down the AD7280A. When the AD7280A acts as a master, the
PD input is supplied from the DSP/microprocessor. When the AD7280A acts as a slave in a daisy chain, the
PD input should be connected to the PDhi output of the AD7280A immediately below it in potential in the
daisy chain.
16
VDD
Positive Power Supply Voltage for the High Voltage Analog Input Structure of the AD7280A. The supply must be
greater than the minimum voltage of 8 V. VDD can be supplied directly from the cell with the highest potential
of the four, five, or six cell battery stacks that the AD7280A is monitoring. The maximum voltage that should
be applied between VDD and VSS is 30 V. Place 10 μF and 100 nF decoupling capacitors on the VDD pin.
17
VSS
Negative Power Supply Voltage for the High Voltage Analog Input Structure of the AD7280A. This input should
be at the same potential as the AGND/DGND voltage.
18
VREG
Analog Voltage Output, 5.2 V. The internally generated VREG voltage, which provides the supply voltage for
the ADC core, is available on this pin for use external to the AD7280A. Place 1 μF and 100 nF decoupling
capacitors on the VREG pin.
19
DVCC
Digital Supply Voltage, 4.9 V to 5.5 V. The DVCC and AVCC voltages should ideally be at the same potential.
For best performance, it is recommended that the DVCC and AVCC pins be shorted together to ensure that
the voltage difference between them never exceeds 0.3 V, even on a transient basis. This supply should be
decoupled to DGND. Place 100 nF decoupling capacitors on the DVCC pin. The DVCC supply pin should be
connected to the VREG output.
20
DGND
Digital Ground. Ground reference point for all digital circuitry on the AD7280A. The DGND and AGND voltages
should ideally be at the same potential and must not be more than 0.3 V apart, even on a transient basis.
