TSM1052 ST Battery Chargers

The TSM1052 is a highly integrated SMPS secondary controller from STMicroelectronics, specifically designed for battery charging applications with constant voltage (CV) and constant current (CC) regulation. For selection, verify supply voltage range, voltage reference accuracy for precise CV regulation, current sense amplifier capability for accurate CC limiting, low operating current for high efficiency, and operating temperature suitable for portable applications. Features include integrated voltage reference and operational amplifiers, low external component count, and flexibility for various battery chemistries. Ideal for battery chargers for Li-Ion, Ni-MH, and lead-acid batteries, AC-DC adapters with CC/CV regulation, power supplies requiring precise voltage and current limiting, and any charging application requiring constant current/constant voltage output characteristic.
