11.1.1 Device Nomenclature

PRODUCT

TPS746)xx(x)PvQWyyyzQ1

xx(x) is the nominal output voltage. For output voltages with a resolution of 100 mV, two digits are used

in the ordering number; otherwise, three digits are used (for example, 28 = 2.8 V; 125 = 1.25 V; 01 =

adjustable).

P indicates an active output discharge feature. All members of the TPS746 family will actively discharge

the output when the device is disabled.

v indicates the topology of the power-good output and the timing associated with the power-good delay.

•

If unused, indicates an open-drain power-good output with a 150-µs delay.

•

If B, indicates an open-drain, power-good output with a 5-ms delay.

•

If C, indicates a push-pull, power-good output with a 150-µs delay.

Q indicates that this device is a Grade-1 device in accordance with the AEC-Q100 standard.

W indicates the package has wettable flanks.

yyy is the package designator.

z is the package quantity. R is for reel (3000 pieces).

Q1 indicates that this device is an automotive grade (AEC-Q100) device.

11.6 Electrostatic Discharge Caution

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with

appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.

ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more

susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
