The ISL88731A from Renesas is a Li-ion Battery Charger Controller IC that is ideal for notebook computers, tablet PCs, and portable applications with rechargeable batteries. It requires an input voltage of 8 - 28 V and provides an output current of up to 8 A. This IC can be programmed using the SMBus system management bus interface and is intended to be used in a smart battery charger (SBC) within a smart battery system. It has a fast response for pulse-charging and a fast system-load transient response. This IC provides high efficiency with a DC/DC synchronous-rectifier buck converter. It offers short-circuit protection (SCP), over-temperature protection (OTP), and over-voltage protection (OVP) that ensures safe operating conditions for better reliability during operation. This RoHS-compliant BMIC is also provided with an evaluation kit to reduce the overall design time. It is available in a surface-mount package that measures 5 x 5 mm.
