Halo Microelectronics has introduced the launch of its HL7009A, a high-efficient 3.6A switching charger IC preferrred for smartphones, pill computing and mobile IoT devices.
The HL7009A is a totally 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 measurement and value by utilizing a specialised technique for exact cost present management and optimising inside energy switches for better effectivity throughout totally different enter voltages, leading to quicker charging instances.
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 equipped 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 totally charged. If the battery voltage drops too low, it restarts charging. The I2C interface allows customizable charging settings and system-level communication. With out an I2C host, a built-in timer ensures secure charging cessation.
It additionally helps the on-the-go (OTG) operate, 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 allows a quicker and extra eco-friendly charging expertise for right this moment’s customers,” acknowledged Halo Microelectronics. “Halo Microelectronics continues to provide stellar battery chargers, and it’s no exception right here with the brand new USB-compliant, totally built-in switch-mode Li-Ion battery charger.”
