产品概述
描述
The STEVAL-ISB041V1 product evaluation board is based on STBC02 battery power management, integrating a linear charger for single-cell Li-Ion batteries with battery protection functions, an LDO regulator, two SPDT load switches and intelligent reset logic.
The device uses a CC / CV algorithm to charge the battery; the fast-charge and pre-charge current can be programmed using an external resistor.
The input supply voltage is used to charge the battery and provide power to the LDO regulator. When an appropriate input voltage is not present and the battery is not empty, the device automatically switches to battery power.
When shutdown mode is activated, the battery power consumption is reduced to less than 100 nA: two embedded 3 Ω SPDT load switches intelligently manage the overall system power consumption. An advanced reset circuit with trigger signal is integrated.
The STEVAL-ISB041V1 can work in standalone mode and a single wire interface can be used to control the STBC02 for full operation. The STEVAL-ISB041V1 evaluation board provides full access to the STBC02 functions through header connectors and can be supplied via a micro-AB USB connector.
