Halo Microelectronics introduced the discharge of its HL7090, a completely computerized and extremely built-in lithium battery charging administration IC with one switching charger, two linear chargers, and full-range programmable cost parameters by means of an I2C suitable interface.
The HL7090 is a compact, versatile, and high-efficiency switching-mode cost administration IC for single-cell Li-ion and Li-polymer batteries utilized in numerous IoT and wearable purposes, together with ear pods. The HL7090 integrates load switches to accommodate USB and wi-fi charging sources. Its built-in buck switching charger can function in increase mode, which powers the linear chargers to cost two equipment concurrently, splendid for earbud purposes. The cost parameters could be programmed by means of the I2C interface (HL7090FN03 model). The IC integrates a synchronous PWM controller, energy MOSFET, enter present sensing, high-accuracy present, voltage regulation, and cost termination perform right into a tiny 3mm x 3mm QFN bundle.
The HL7090 gives absolutely computerized three-phase battery charging management, together with trickle cost, constant-current cost (CC), and fixed voltage cost (CV) till the battery reaches the cost termination voltage. The enter present is routinely restricted to the worth set by the host, and the charging is terminated based mostly on the battery voltage and a user-selectable minimal present stage. A security timer with reset management gives a security backup for the I2C interface.
Throughout regular operation, the HL7090 routinely restarts the cost cycle if the battery voltage falls under an inside threshold and routinely enters sleep mode, or excessive impedance mode when the enter provide will not be appropriately linked. The cost standing could be reported to the host by means of the I2C interface.
“Our new Li-ion battery switching charger IC with its absolutely computerized cost administration takes all the troubles out of charging IoT purposes, offering comfort, no problem, and peace of thoughts,” mentioned David Nam, CEO of Halo Microelectronics.”
