The PS700 is a cost-effective, highly accurate IC that measures, stores and reports all of the critical parameters required for rechargeable battery monitoring with a minimum of external components. It precisely measures charge/discharge current as well as voltage and temperature of a battery pack. In addition, the PS700 accurately accumulates both charge and discharge current as independent parameters. Temperature history can also be maintained for calculating self-discharge effects.

Battery Monitor with:
• Integrated voltage regulator
• Precision time base, temperature sensor
• 512 byte EEPROM, 32 byte RAM
• Programmable 16-bit sigma-delta A/D converter
• SMBus/I2C™ compatible
