MAX17823B

12-Channel High-Voltage Data Acquisition System

General Description

Benefits and Features

The MAX17823B is a data acquisition system for the

management of high-voltage battery modules. The

system features a 12-bit SAR ADC that can measure

12 cell voltages and two temperatures in 161 µs.

There are 12 internal switches for cell-balancing and

extensive built-in diagnostics. Up to 32 devices can

be daisy-chained together to manage 384 cells and

monitor 64 temperatures.

•

AEC-Q100 Grade 2 Temperature Range

-40°C to 105°C

•

Operating Voltage from 9V to 65V

Ultra-Low Power Operation

Standby Mode: 2mA

Shutdown Mode: 2µA

•

12 Cell-Voltage Measurement Channels

2mV Accuracy (3.6V, +25°C)

5mV Accuracy (0°C to +45°C)

10mV Accuracy (-40°C to +105°C)

Cell voltages (0V to 5V) are measured differentially

over a 65V common-mode range. Cell measurements

have a typical accuracy of 2mV (3.6V cell, 25°C). If

oversampling is enabled, up to 128 measurements

per channel can be averaged internally with 14-bit

resolution. The system can shut itself down in the

event of a thermal overload by measuring its own die

temperature.

12 Cell-Balancing Switches

Up to 150mA per switch

Emergency Discharge Mode

•

Two Temperature Measurement Channels

Die Temperature Measurement

Automatic Thermal Protection

29 Voltage Threshold Alerts

The system uses Maxim’s battery-management

UART protocol for robust communications and when

used in conjunction with the MAX17880 12-channel

battery monitor, it is ideal for automotive battery-

management systems that require a high safety

integrity level.

12 Over-Voltage Faults

12 Under-Voltage Faults

Two Over-Temperature Faults

Two Under-Temperature Faults

One Cell Mismatch Alert

(highest cell versus lowest cell)

•

Four GPIOs

Built-in Diagnostics to Support ASIL D and

FMEA Requirements

Applications

•

High-Voltage Battery Stacks

Electric Vehicles (EVs)

Hybrid Electric Vehicles (HEVs)

Electric Bikes
