Halo Microelectronics, a maker of analog and power management integrated circuits enabling energy-efficient smart systems, announced the launch of its HL7136 device. The HL7136 device is an UFCS (universal fast charging standard) fast charging protocol charger for 1-cell Li-ion and Li-ion polymer batteries.
The HL7136 is an UFCS low-voltage fast direct charger that integrates a dual-phase switched-capacitor converter and reverse blocking MOSFET (metal-oxide-semiconductor field-effect transistor), achieving a 97.4% efficiency for 4.5V output and 5A charging current with 2×22µF per phase. The device utilises a switched capacitor converter architecture along with an integrated FET (field-effect transistor) for optimal performance.
This design enables efficient operation with a 50% duty cycle in the Charge Pump (CP) mode. By using the CP mode, the output voltage (VOUT) can be approximately half of the input voltage (VIN), while the output current is doubled compared to the input current. This configuration helps minimise losses over the input power cable and prevents excessive temperature rise in the application.
The HL7136 also features a Bypass (BP) Mode. In BP Mode, the internal power FETs allow the (VIN) to pass directly to (VOUT) without undergoing any conversion process. This mode provides a straightforward path for the input voltage, catering to specific applications where voltage conversion is unnecessary. Furthermore, the device includes a thermal regulation loop to address any potential overheating issues that may arise during the CV/CC (Constant Voltage/Constant Current) regulation process.
The HL7136 is equipped with all the necessary protective measures. For a complete list along with a full product description and features, please visit Halo Microelectronics.
“The UFCS is a new protocol soon to be adopted by smartphone manufacturers globally and we are thrilled that our dual-phase 40 W charge pump charger with its low-power fast charging perfectly aligns with this protocol,” says David Nam, CEO of Halo Microelectronics.
