ADES1754/ADES1755/ADES1756
General Description
The ADES1754/ADES1755/ADES1756 are flexible
data-acquisition systems for the management of high-
voltage and low-voltage battery modules. The systems
can measure 14 cell voltages and a combination of six
temperatures or system voltage measurements with fully
redundant measurement engines in 162µs, or perform
all inputs solely with the ADC measurement engine in
99μs. Fourteen internal balancing switches rated
for >300mA for cell-balancing current support extensive
built-in diagnostics. Up to 32 devices can be daisy-
chained to manage 448 cells and monitor 192
temperatures.

Current
Cell and bus-bar voltages ranging from -2.5V to +5V are
measured differentially over a 65V common-mode
range, with a typical accuracy of 100µV. If oversampling
is enabled, up to 128 measurements per channel can be
averaged internally with 14-bit resolution and combined
with digital post-processing IIR filtering for increased
noise immunity.
• Automated Balancing with Individual Cell Timers
• Automated Balancing by Cell Voltage
• Emergency Discharge Mode
•
Six Configurable Auxiliary Inputs for Temperature,
Voltage, or GPIO
Integrated Die Temperature Measurement
Automatic Thermal Protection
Hot Plug-Tolerant without External Protection
Individually Configurable Safety Alerts

•
The system can shut itself down in the event of a thermal
overload by measuring its own die temperature. The
system uses Analog Devices' battery-management
UART protocol for robust communications and supports
2
an I C controller interface for external device control. It
is optimized to support a reduced feature set of internal
diagnostics and rapid-alert communication through both
embedded communication and hardware-alert interfaces.
