Halo Microelectronics has introduced the launch of its HL7009A, a high-efficient 3.6A switching charger IC supreme for smartphones, pill computing and cellular IoT units.

The HL7009A is a completely built-in, all-in-one switch-mode Li-Ion battery charger IC that may cost a single cell with a most present of three.6A. It simplifies charging by eradicating energy path administration, making it an economical and compact resolution. Moreover, it improves charging effectivity and reduces dimension and price through the use of a specialised technique for exact cost present management and optimising inside energy switches for higher effectivity throughout totally different enter voltages, leading to sooner charging occasions.

It helps a variety of enter sources, together with the usual USB host port, USB charging port and the AC-DC adapter. It’s appropriate with enter working voltages starting from 4.0V to 9.5V, enabling it to energise the system rail even within the absence of a battery. Moreover, it’s geared up to facilitate BC1.2 detection, making certain the appliance of an applicable enter present restrict for optimum utilisation of the facility provided by the enter supply.

The HL7009A independently handles Li-ion battery charging when linked to an I²C host. It oversees battery voltage, executes charging in three phases: pre-charge, fixed present, and fixed voltage, and stops when absolutely charged. If the battery voltage drops too low, it restarts charging. The I²C interface permits customizable charging settings and system-level communication. With out an I²C host, a built-in timer ensures protected charging cessation.

It additionally helps the on-the-go (OTG) perform, permitting for configurable output voltage at VBUS, with a most output present reaching as much as 1.2A.

“The HL7009A with its exceptionally excessive effectivity permits a sooner and extra eco-friendly charging expertise for at the moment’s shoppers,” said Halo Microelectronics. “Halo Microelectronics continues to provide stellar battery chargers, and it’s no exception right here with the brand new USB-compliant, absolutely built-in switch-mode Li-Ion battery charger.”
