Description
HL7016 is a fully integrated switch-mode Li-ion battery charger with power MOSFET, power path management, I2C interface and USB On-The-Go (OTG) boost function. It can be used with single cell or multiple-cell in parallel Li-ion and Li-polymer batteries in a wide range of cell-phones, smart phones, tablets, power banks and other portable devices. It’s switch-mode operation and low-resistance power path maximize charging, discharging and boost efficiency, reduce battery charging time and extend battery life during the discharging phase.
This device supports a wide range of input sources, including standard USB host port, USB charging port and high power AC-DC adapter. It supports an input operating voltage from 3.9V to 12V, and can power up the system rail without a battery. It can automatically adjust to the maximum power output of the input source via the input dynamic power management control (INDPM).
HL7016 manages the complete charging cycle of a Li-ion battery autonomously with or without the presence of an I2C host. It detects the battery voltage and automatically charges the battery in four phases: trickle charge, pre-conditioning, constant current and constant voltage. It automatically terminates charging when the battery is full, and re-starts a charging cycle if the battery voltage falls below the recharge threshold. For a short-circuit protected battery, it can reactivate the battery by providing a float
voltage to the battery terminal before charging starts. Its I2C interface provides maximum programmability for charging parameters and system-level communication. When the I2C host is not present, a built-in watchdog timer stops charging after the timer expires to assure safety battery operation.
A built-in low-resistance power path management system enables instant power-up of the system rail when an input source is plugged in, even with a shorted battery or no battery. When a valid battery is present, it provides battery assistant mode during charging when the system load exceeds the capacity of the input source.
The USB OTG boost function provides a programmable 4.55V~5.5V boost output at VIN port from the battery, and supports up to 2.1A of current.
HL7016 integrates comprehensive protections mechanism to ensure safe operation of the battery, including battery temperature monitoring via negative temperature coefficient (NTC) thermistor, charging safety timer, over-voltage and under-voltage detection. The device also provides output over-current protection, and regulates its on-chip junction temperature to be no more than 120℃ by regulating its charging current. HL7016 is available in a 24-pin 4mm x 4mm QFN
