ISL95908

The ISL95908 is a Power Management Integrated Circuit (PMIC) for ultrabook, notebook, and tablet computers powered by 2-cell Li-ion batteries. It integrates control, MOSFET drivers, power MOSFETs, fault protection, and fault monitoring functions for eight highly efficient synchronous buck regulators and VTT LDO. It is offered in a thermally efficient 5.5mm x 5.5mm, 121-bump, 0. 5mm pitch WLCSP package. The PMIC regulators convert system voltage from the battery or adapter into all platform voltages needed for a typical computer system including 5V and 3.3V system regulators, 1.8V/2.5V, 1V, 0.975V, 0.9V for controller-hub, peripheral and core voltages, as well as programmable VDDQ and VTT regulators for DDR3/3U/3L, LPDDR3, and DDR4 voltages. The switching regulators operate at 1MHz and are based on Intersil’s proprietary R4™ Technology, which provides high light-load efficiency, fast transient response, seamless DCM/CCM transitions, and requires no external compensation. The PMIC provides overcurrent, overvoltage and over-temperature fault protections, and undervoltage and over-temperature warnings. A temperature alert signal indicates the PMIC is operating at an elevated temperature and ALERT indicates if any other fault or warning has occurred. The PMIC also offers significant I²C capability and can be configured to provide eight GPIO pins for additional system functionality and each regulator has an independent power-good indicator.
