Description

The HX7605 is a complete, cost effective, high-efficient solution that is ideal for Li-Ion Battery Powered Mobile Supply.

VBAT is a complete switch-mode battery charger for one cell (4.2V) lithium-ion battery. The VBAT provides a small, simple and efficient solution to fast charge Li-ion battery with maximum charge current programmable up to 1.3A, set using an external current sense resistor.

VOUT5 (5.05V) is a step-up DC-DC converter with internal power MOSFETs. It achieves 2A (with NMOS 2318) continuous output current over a wide input supply range with excellent load and line regulation.

The HX7605 is available in a low profile SSOP-16L package.
