ISL95901IRZ-T

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 8 highly efficient synchronous buck regulators and VTT LDO. It is offered in a thermally efficient 5.5mmx5.5mm, 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 8 GPIO pins for additional system functionality and each regulator has an independent power-good indicator.
