Power Bank IC with 1A Linear Charger and

1.2A Boost Converter

General Description

The HM5902 is a highly integrated Power Bank IC with a Linear Li-Ion Charger up to 1A charge

current and 1.2A output current Asynchronous Boost Converter. With few external components, the

HM5902

could enable Charger and Booster simultaneously and is well suited for portable power bank

applications. In shutdown mode, reverse battery current IBAT will be reduced to below 6uA.
