STEVAL-ISB035V1 Li-Ion/Li-Po battery power management evaluation board based on STBC03 Data brief 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. Features Two 3- SPDT load switches with dedicated Charges single-cell Li-Ion/Li-Po batteries control input are embedded to intelligently with CC-CV algorithm and charge manage overall system power consumption. The termination STEVAL-ISB035V1 can work in standalone Fast charge current programmable from 1 mode, but several digital inputs can be used to mA to 650 mA control the STBC03 for full operation. Pre-charge current programmable from 1 The STEVAL-ISB035V1 evaluation board mA to 650 mA provides full access to STBC03 functions through Adjustable floating voltage up to 4.45 V header connectors and can be supplied through Integrated always-ON low quiescent LDO a micro-AB USB connector. regulator Battery overcharge and over-discharge protections Overcurrent protection Shipping mode entry and exit inputs Integrated dual 3 SPDT load switches Digital control inputs RoHS compliant September 2017 DocID029360 Rev 1 1/4 www.st.com For further information contact your local STMicroelectronics sales office Schematic diagram STEVAL-ISB035V1 1 Schematic diagram Figure 1: STEVAL-ISB035V1 circuit schematic 2/4 DocID029360 Rev 1
