Announcement: Introducing HL8545/G: Quad-Channel 50 mΩ High-Side Switch for Advanced Automotive Applications


The HL7601 provides a power supply solution for products powered by Li-ion battery. By combining built-in power transistors, synchronous rectification, and low supply current, this IC is optimized for single-cell portable applications like smartphones or tablet PCs. 

The HL7601 is a boost regulator designed to provide a minimum output voltage from a single-cell Li-ion battery even when the battery voltage is below system minimum. This extends the battery run time and overcomes input current and voltage limitations of the powered system. The output voltage regulation is guaranteed up to a maximum load current of 2A. The regulator has a smooth transition between a bypass mode and a normal boost mode. The device can be forced into the bypass mode to reduce a quiescent current. 

The HL7601 is available in a 16-bump, 0.4mm pitch, wafer-level chip-scale package (WLCSP).
