Isl 9538H(intersil)

• Function: It acts as a specialized notebook battery power management and charging controller. It utilizes a buck-boost topology, meaning it can cleanly convert higher input voltages down (buck) or lower input voltages up (boost) to power the laptop system and charge the battery.
• Input Architecture: It manages multiple power sources seamlessly, typically choosing between a standard DC power jack, a USB Type-C power delivery port, or the internal battery.
• Package Type: It comes in a compact 32-lead 4x4 mm TQFN surface-mount package.
• Communication Interface: Uses the SMBus interface to report battery metrics and receive software commands from the system's embedded controller (EC)
