HL7132D

The HL7132D is the low voltage fast direct charger for 1 cell Li-ion and Li-polymer batteries. The device integrates a dual phase switched capacitive converter, a reverse blocking MOSFET (QRB FET) and shows 97.37% efficiency at 4.5V output and 4A current with flying capacitor,1×22µF, per phase at fSW=1.1MHz. The device features two different switching modes, 2:1 and 1:2 CP mode. The 2:1 CP mode allows the output voltage, VOUT, to be around half of the input voltage, VIN, and the output current to be double of the input current. In 1:2 CP mode, a voltage at VIN will be double of VOUT voltage. The HL7132D provides CC (Constant Current) and CV (Constant Voltage) regulation through controlling the QRB FET for a safe charging operation in 2:1 CP mode. CC regulation is controlled through a close loop of the input current sensing or battery current sensing and CV regulation is controlled through a close loop of the battery voltage sensing. In addition, HL7132D also supports thermal regulation loop in case CV/CC loop causing device over-heat during regulation operating in 2:1 CP mode.
