Description

The STEVAL-ISB035V1 is an evaluation board

based on the STBC03 battery power

management IC, integrating a linear charger for

single-cell Li-Ion batteries with battery protection

functions, an LDO regulator and two SPDT load

switches.

The device uses a CC-CV algorithm to charge

the battery; the fast-charge and pre-charge

currents 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 a valid input voltage is not present and the

battery is not empty, the device automatically

switches to battery power.

When shutdown mode is activated, battery power

consumption falls to less than 100 nA.

Two 3-

Ω SPDT load switches with dedicated

control input are embedded to intelligently

manage overall system power consumption. The

STEVAL-ISB035V1 can work in standalone

mode, but several digital inputs can be used to

control the STBC03 for full operation.

The STEVAL-ISB035V1 evaluation board

provides full access to STBC03 functions through

header connectors and can be supplied through

a micro-AB USB connector.
