GLF1421 is listed in the Power Distribution Switches, Load Drivers range at ChipApex. The manufacturer field lists GLF Integrated Power. Its product description is Dual Channel, IQSmartTM Load Swi. Review the specifications below when checking this part for your BOM.
The GLF1421 is a power load switch from GLF Integrated Power featuring true reverse current blocking (TRCB) at both on and off states. It integrates slew rate control to manage inrush currents. The device is designed for efficient power distribution in compact electronic systems.
Verify the specific package variant and tape & reel quantity against the official datasheet before ordering. Confirm that the TRCB and slew rate features align with the target application's electrical requirements. Ensure compatibility with the system voltage levels and thermal constraints specified by the manufacturer.
Select this component when reverse current isolation is required during both conduction and shutdown phases. The integrated slew rate control makes it suitable for applications sensitive to input voltage droop or EMI during turn-on. Evaluate the package size constraints against the available WLCSP options.
This part belongs to the GLF Integrated Power portfolio of intelligent power switches. It complements other IQ Smart™ series devices like the GLF71301, focusing on nano-current consumption and advanced protection features for modern low-power embedded systems.
Check for direct pin-compatible substitutes within the GLF family, such as variants with different current ratings or additional protection features. Verify that any alternative maintains the true reverse current blocking capability if critical to the design.
