The MAX17330 is not recommended for new designs. The replacement part is the MAX17332.

The MAX17330 is a 28μA I_Q stand-alone charger, fuel gauge, protector, and battery internal self-discharge detection IC for 1-cell lithium-ion/polymer batteries. When a voltage source is present, the MAX17330 regulates charging by modulating the charge N-FET, using AccuCharge™ charger technology. The MAX17330 regulates charge voltage, current, and FET temperature. Stand-alone charging is supported by flexible configuration in nonvolatile memory. The IC supports the following:

• Low-Power Charging
  • 1mA to 500mA directly from universal 5V USB
  • No USB identification/coordination needed
• High-Power Parallel Packs (>1000mA)
  • Independently charges parallel packs
  • Prevents cross-charging for parallel batteries
  • Coordinates external DC-DC with alerts
  • Minimizes dropout and heat
• Protection and Charging Control —pack or host side

The MAX17330 ideal diode circuit supports a quick response to system transients and adapter removal with low voltage drop across the CHG FET.

The IC uses the ModelGauge™ m5 EZ algorithm that combines the short-term accuracy and linearity of a coulomb counter with the long-term stability of a voltage-based fuel gauge to provide industry-leading accuracy. The IC automatically compensates for cell aging, temperature, and discharge rate while providing accurate state-of-charge (SOC) in milliampere-hours (mAh) or percentage (%) over a wide range of operating conditions.

The IC monitors the voltage, current, temperature, and state of the battery to provide protection against over/undervoltage, overcurrent, short-circuit, over/undertemperature an
