STMicroelectronics presents the STEVAL-ISB032V1, a comprehensive evaluation board engineered for power management of single-cell Lithium-ion batteries using the STNS01 linear charger IC. Designed to facilitate development and testing of battery charging circuits, this kit integrates a linear charger and an LDO regulator alongside robust battery protection features. The board operates using a constant current/constant voltage (CC/CV) algorithm, allowing the fast-charge current to be precisely programmed via external resistors.
The floating voltage is set at 4.2V, which is compatible with standard Lithium-ion battery requirements. Both pre-charge and termination currents are scaled automatically, ensuring safe battery operation and effective charge management. With dual powering options, the board charges batteries directly from an input supply voltage, and when this input is absent but the battery still retains charge, it seamlessly transitions to battery power to maintain output functionality.
The STNS01 IC on this evaluation board incorporates safety protections, including overcharge, over-discharge, and overcurrent sensing circuits, guarding the battery against common fault conditions and prolonging battery life. Its integrated LDO regulator further extends system capability, ensuring stable output for connected devices or subsystems.
Developers and engineers may use this kit to evaluate, optimize, and design battery charger circuits within electronic, robotics, and portable device applications. The STEVAL-ISB032V1 is ideally suited for integration into educational projects, proof-of-concept prototypes, or commercial product development requiring robust charging and power management features for Lithium-ion batteries.
Certified to RoHS environmental standards, the board is manufactured in Italy and supports reliable, Safe, and standards-compliant operation. Typical application areas include embedded devices, IoT modules, consumer electronics, STEM educational kits, and portable robotics.
