UCD3138128A: UCD3138 family Reset

Part Number: UCD3138128A
Other Parts Discussed in Thread: UCD3138, TIDA-00705, TIDA-00653, PMP4320A, UCD3138064A, UCD3138128, UCD3138A64, UCD3138A, , UCD3138CC64EVM-030

Hi,

slua779a UCD3138 Family - Practical Design Guideline states the following:

"The RESET pin must have one at least 2.2-μF low ESL capacitor locally decoupled with DGND plane or
SGND plane. As shown in Figure 2-1, this capacitor must be placed very close to the device RESET pin."

Looked at the following TI designs:

PMP11432: no capacitor

TIDA-00705: uses a 100n capacitor

TIDA-00653: uses a 100n capacitor

PMP4320A: uses a 100n capacitor

and so on. Am I missing something here ?

Thanks,

Manu
