A chip originally intended for voltage monitoring and identification of battery packs, made interesting and useful by its 10-bit A/D converter. Interface bus: 1-Wire (OneWire). Multiple devices can be placed on the same bus. Each chip has its own serial number and E2PROM memory for its own use.

• 10-bit A/D converter
  • wide input voltage range up to 10V
• A dedicated A/D converter for monitoring charging current runs in the background at 16Hz
  • Uses an external sense resistor (e.g. 0,1ohm) connected to the Vsens pins
  • Note! The chip enters sleep mode if no measured charging current is present (AZ model stays awake)
• Chip has a 64-bit unique serial number
• 40 bytes of persistent EEPROM memory
• Built-in 13-bit temperature measurement across the chip's temperature range
• Operating temperature: -40...+85°C
