Li-Battery Protection ICs

WXNSIC NST03AA is a highly integrated Bluetooth charging dock SoC combining lithium battery charge management, a synchronous boost converter, power path management, and battery protection in a single compact device — purpose-built for wireless audio accessories and USB-charged portable docks. Accepting an input voltage of 4.5V to 5.5V, the NST03AA delivers a 300mA charge current while its synchronous boost converter supports a 0.7A output, all with an ultra-low standby current of just 5µA (I_q). Integrated power path management enables simultaneous charge and discharge with built-in short-circuit and heavy-load protection, eliminating the need for an external diode. ABL Semi supplies the NST03AA in an SOP-8 package with flexible MOQ, 100% authentic factory-original stock, and compliance-friendly UK trade documentation.

CR MICRO PT6010E is a high-voltage multi-cell lithium battery protection IC designed to safeguard 8–10 series Li-ion, LiFePO4, and lithium titanate battery packs against overcharge, over-discharge, overcurrent, and over-temperature conditions across an operating voltage range of 5V to 60V. The PT6010E delivers precise protection with a ±25mV overcharge detection voltage accuracy and ±10mV discharge overcurrent detection accuracy, while independently configurable charge and discharge over-temperature thresholds via external resistors give designers flexible thermal management without firmware overhead. With a quiescent current of just 20µA (I_q) and direct drive capability for external N-type charge and discharge MOSFETs, the device is well suited to high-voltage e-bike, energy storage, and industrial battery pack applications. ABL Semi supplies the PT6010E in an LQFP-32L (7×7mm) package with flexible MOQ and 100% authentic, factory-original stock.
