Table 8-1 Device Nomenclature
PRODUCT(1) VOUT
TPS74801Q(W)yyyzM3Q1 Q indicates that this device is a grade-1 device in accordance with the AEC-Q100 standard.

W indicates that the package has wettable flanks (new chip only).


yyy is the package designator.
z is the package quantity.
M3 is a suffix designator for devices that only use the latest manufacturing flow (CSO: RFB). Devices without this suffix can ship with the legacy chip (CSO: DLN) or the new chip (CSO: RFB). The reel packaging label provides CSO information to distinguish which chip is being used. Device performance for new and legacy chips is denoted throughout the document.
Q1 indicates that this device is an automotive grade (AEC-Q100) device.
