描述The MAXREFDES1289 reference design evaluates the MAX17852/MAX17853 for 400V four-wheeler Battery Management Systems (BMS).
This design showcases capabilities of the MAX17852/MAX17853, like individual 14-cell voltage measurements, pack-voltage, temperature (up to four sensors using General Purpose Inputs/Outputs (GPIOs)), pack-current measurement (MAX17852 only), and passive cell balancing.
The MAX17852/MAX17853 support ASIL-D requirements for cell voltage, temperature, current, communication, and Failure-Mode Effects Analysis (FMEA).
Up to 112 cell voltage measurement with ±2mV accuracy at 5°C to 40°C.
Supports flexi-pack configuration.
Pack-current measurement using external current-sense resistor.
Passive cell balancing up to 300mA with internal switch, with odd/even cell balancing scheme (single cell or group).
- Auto cell balancing configuration with undervoltage (UV) threshold and timer options.
- Manual cell balancing configuration.
Four configurable auxiliary inputs for temperature, voltage, or GPIO.
Internal die temperature measurement. Individually configurable safety alert.
- Overvoltage (OV), undervoltage (UV), overtemperature, and undertemperature faults.
- One cell mismatch alert.
Selectable Universal Asynchronous Receiver-Transmitter (UART) or Serial Peripheral Interface (SPI).
UART configurations with Packet Error Checking (PEC).
- Dual UART configuration with redundancy.
- Single UART configuration.
Single-side component placement.
Compatible with MAX17852EVKIT software along with MINIQUSB board.
