The HL7026, a 3A switch-mode fast Li-Ion battery charger IC, has passed the certification of MTK platform (MT8375), and is adopted to it’s tablet platform reference design.
Better performance than HL7005, the HL7026 fast charger has a maximum charging current up to 3A, and the integrated USB OTG boost output up to 5V/2.1A. Built-in power path management, ensures that system is open for any battery conditions.
• Integrated MOSFET, 1.5MHz Synchronous PWM, and support small 1-2.2uH inductor;
• VDP and IDP auto adjust to actual adaptor power capacity;
• Integrated USB detection (PSEL);
• Built in battery activation function to solve system crash caused by battery short circuit;
• System reset function: == battery removal;
• Built in shipping mode with extremely low standby power consumption.
