HL7136

The HL7136 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 and reverse blocking MOSFET (QRB FET) and shows 97.4% efficiency for 4.5V output and 5A charging current with 2x22uF per phase. The switched capacitor converter architecture of this device and the integrated FET are optimized to enable a 50% duty cycle operation under Charge Pump (CP) Mode. The 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, reducing the losses over the input power cable as well as limiting the temperature rise in the application. The dual-phase architecture reduces the input capacitance requirements as well as reducing the input voltage ripple. Besides CP Mode, the device also has Bypass (BP) Mode. BP Mode allows VIN forwardly passing through internal power FETs to VOUT without any conversion. The HL7136 provides CC regulation and CV regulation through controlling the QRB FET for a safe charging operation. 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, HL7136 also supports thermal regulation loop in case CV/CC loop causing device over-heat during regulation operating. The HL7136 has all the necessary protections to ensure the safe operation. The device includes OTP (Over-Temperature Protection), VIN UVP/OVP, IIN OCP/UCP, VOUT OVP/UVP, VBAT OVP, IBAT OCP, PMID to VOUT OV/UV, CFLY SCP (Short Circuit Protection), VIN SCP, VOUT SCP and Watchdog Timer. Besides all the protections above, HL7136 also features 12-bit ADC that can offer VIN, IIN, VOUT, VBAT, IBAT, VTS, TDIE information to system for optimizing charging control. HL7136 is available in a 36-Bump WLCSP package with 2.65mm x 2.61mm size.
