The LP6400 from LOWPOWER is an 18W fast charge synchronous buck regulator built for high-voltage charging solutions. It supports an input voltage range of 8V to 32V and delivers a continuous 3.6A output current at 5V, compatible with QC2.0/3.0, Huawei FCP, Samsung AFC and other mainstream fast charging protocols. With low on-resistance internal MOSFETs and multiple protection functions, this SOP-8 IC greatly cuts down the use of external components. As a UK-based distributor, ABL Semi provides 100% original LP6400 with flexible MOQ and reliable pin-to-pin replacement services.

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.

Prisemi PSC2945 is a highly integrated single-cell Li-ion/Li-polymer battery charger IC combining a switch-mode charger and boost regulator, designed to minimise charging time from USB power sources while enabling USB OTG output from the battery. Supporting an operating input voltage range of 3.2V to 12V, the PSC2945 delivers up to 3A maximum charge current with ultra-low quiescent current of just 10µA (I_q), making it well suited for portable consumer electronics, wearables, and USB-powered handheld devices. Configuration and monitoring are handled via a flexible I²C serial interface, enabling precise control of charging parameters and system settings. ABL Semi supplies the PSC2945 in a compact QFN-24L (4×4mm) package with flexible MOQ, supporting both prototype builds and high-volume production runs with 100% authentic, factory-original components.

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.

UMW TP4056 is a high-performance single-cell Li-ion battery linear charger IC utilising a constant current/constant voltage (CC/CV) charging architecture, designed for compact portable products powered by USB or adapter supplies. Supporting an input voltage range of 4V to 6.5V, the TP4056 fixes the charge termination voltage at 4.2V with an externally programmable charge current, and enters a low-power sleep state drawing less than 1µA battery leakage when the input is disconnected. A standby quiescent current of just 35µA (I_q) and support for 0V battery charging make the UMW TP4056 particularly well suited to deeply discharged cell recovery in power banks, wearables, and IoT devices. ABL Semi supplies the UMW TP4056 in an ESOP-8 package with flexible MOQ and 100% authentic, factory-original stock.
