The ERB1000AWC9 is a highly integrated Li-ion charger, integrates a high accuracy linear charger of programmable charging current (up to 456mA).The device integrates advanced power path management and control that allows the device to provide power to the system while charging the battery even with poor adapters.The dynamic power path management is able to automatically balance the currents delivered to the system and battery charging. A high voltage and over current protection circuit is implemented in the IC to protect it from high input voltage as high as 36V.
The ERB1000AWC9 device supports charge current up to 456mA and supports termination current down to I mA.The maximum charge current is set at a default of 128mA and is programmable via I2C. The battery is charged using a standard Li-ion charge profile with three phases: pre-charge, constant current and constant voltage regulation.The device has several power saving modes to increase battery life whether the product is in storage or in operation.The ERB1000A is available in CSP-9 package.
