| Evaluation Boards | 1 | Active | The STC3117 includes the STMicroelectronics OptimGauge™ algorithm. It provides accurate battery state-of-charge (SOC) monitoring, tracks battery parameter changes with operation conditions, temperature and aging, and allows the application to get a battery state-of-health (SOH) indication.
An alarm output signals low SOC or low voltage conditions and also indicates fault conditions like a missing or swapped battery. |

STEVAL-ISB033V1Evaluation board for STBCFG01 single-cell Li+ battery charger with OTG boost, voltage mode fuel gauge and 200 mA LDO | Evaluation and Demonstration Boards and Kits | 1 | Active | The STEVAL-ISB033V1 is an evaluation board to test the first-of-its-kind STBCFG01 switch mode battery charger for single cell Li-Ion batteries, which integrates a highly accurate voltage mode fuel gauge to monitor a battery's state of charge. The device also provides a 5 V output to supply USB OTG (on-the-go) bus-powered devices in addition to an LDO linear voltage regulator to support system boot in dead battery conditions.
The STBCFG01 uses accurate measurements of the battery voltage which allows the estimation of the battery's state-of-charge (SOC) without a current-sensing resistor. The switching charger works together with the fuel gauge to simplify monitoring features and to save current consumption when the device is not charging. The battery charger features a smart input current limit; the maximum input current can be selected through the I²C interface, and if the input voltage drops below a programmable threshold, even if the selected maximum current limit current has not been reached yet the dynamic input current limit function is activated, preventing the input current from increasing further. The dynamic input current limit function can be disabled, if necessary. An automatic input pre-bias load makes the device suitable for applications using voltage sources requiring a minimum external load for correct regulation. |
| Development Boards, Kits, Programmers | 1 | Active | The STEVAL-ISB037V1 board features the LD39020 high performance linear voltage regulator, configured to convert a DC input voltage from 2.4 V to 5.5 V into a precise and stable 1.8 V output voltage.
Only two small ceramic capacitors are needed to implement the linear regulator solution.

The STEVAL-ISB047V1 evaluation kit is a full solution, complete with boards, firmware, a GUI for debugging, schematics, layout files and bill of materials.
Tools for STEVAL-ISB047V1 are available on www.st.com, and allow users to access runtime information such as power delivered, regulation error and protocol status. Parameters can also be adjusted with these tools. |
STEVAL-ISC002V1Resonant LCC 90 W notebook power adapter based on the L6599 and STP9NK50ZF | Development Boards, Kits, Programmers | 1 | Obsolete | This demonstration board is a 90 W wide-range mains AC-DC adapter which is power factor corrected. Its electrical specifications are suitable for typical high-end portable computer power adapters. The particular benefits of this design are the very low no-load input consumption (<0.5 W) and the very high global efficiency.
The architecture is based on a two-stage approach: a front-end PFC pre-regulator based on the L6563 TM PFC controller and a downstream multi-resonant half-bridge converter that makes use of the L6599 resonant controller. |
STEVAL-ISC003V1STUSB4710 evaluation board USB PD controller with on-board DC-DC | Evaluation Boards | 1 | Obsolete | The STEVAL-ISC003V1 evaluation board is a ready-to-use USB PD source using the STUSB4710 and ST1S14 ICs. It is used to demonstrate the features of the STUSB4710 controller by converting a single-voltage power supply into a Type-C power delivery source.
The STUSB4710 controls the Type-C port ensuring power delivery advertising and negotiation, controls the DC-to-DC converter and power paths, and monitors VBUSvoltage.
The ST1S14 device ensures the step down conversion from the input DC port to the negotiated VBUSvoltage.
