ADP198ACBZ-R7 is listed in the Power Distribution Switches, Load Drivers range at ChipApex. The manufacturer field lists Analog Devices Inc.. Its product description is IC PWR SWITCH P-CHAN 1:1 4WLCSP. Review the specifications below when checking this part for your BOM.
The ADP198ACBZ-R7 is a high-side power switch IC designed for power distribution applications. It supports an operating supply voltage range of 1.65 V to 6.5 V and delivers a maximum output current of 1 A. The device features a maximum on-resistance of 90 mOhms and a maximum run time of 450 µs. It is housed in a WLCSP-4 package and operates within a temperature range of -40°C to +85°C.
Verify the specific suffix variant, as the provided model lacks the final digit present in some distributor listings (e.g., ADP198ACBZ-11-R7). Confirm RoHS compliance status and ensure the WLCSP-4 footprint matches the target PCB layout. Check for any regional sales restrictions or limited availability notices associated with this component series.
Select this component when a compact, single-channel high-side switch is required for loads up to 1 A. Ensure the input voltage stays within the 1.65 V to 6.5 V range. Consider the 90 mOhm on-resistance for thermal management in dense layouts. Verify that the 450 µs run time meets system timing requirements for load activation.
This part belongs to the ADP198 series of power distribution switches from Analog Devices. It complements other PMIC offerings by providing simple, protected switching for low-power rails. The series focuses on minimizing external component count while integrating essential safety features like thermal shutdown and current limiting for robust system operation.
Publicly confirmed substitute part numbers are not available in the provided documentation.
