General Description

DQ VAD VSENS+ VSENSNC GND AGND X2 X1 VDD - Data In/Out - General A/D input - Battery current monitor input (+) - Battery current monitor input (-) - No connect - Digital Ground - Analog Ground - Connection for 32.768 kHz XTAL - Connection for 32.768 kHz XTAL - Power Supply (2.7V to 10.0V) DESCRIPTION The DS2437 Smart Battery Monitor provides several functions that are desirable to carry in a battery pack: a means of tagging a battery pack with a unique serial number;

a direct-to-digital temperature sensor which eliminates the need for thermistors in the battery pack;

an A/D converter which measures the battery voltage and current;

Key Features

  • Unique 1-Wire interface requires only one port pin for communication Provides unique 64-bit serial number to battery packs Eliminates thermistors by sensing battery temperature on-chip On-board A/D converter allows monitoring of battery voltage for end-of-charge and end-ofdischarge determination On-board integrated current accumulator facilitates gas gauging Real-time clock in binary format 40-byte nonvolatile user memory available for storage of user data such as gas gauge and manufacturing inf.
