Part Number:TPS3808-Q1
Hi team,
Can you please answer about below questions of TPS3808-Q1?
1. The timing spec of MR reset is typ. 1ns in the datasheet. From a MR reset spec point of view, is it good, or too short duration?
2. If there is a noise on the MR line, the MR input which has the 1ns spec might recognize the noise as an input. Do you think so?
3. The customer’s schematic has a 4.7kohm pull up on the MR line. So, the total resistor of internal/external pull up will be about 4.5kohm, even if
the datasheet recommends over 10kohm. Is it okay for the external 4.7kohm?
4. In addition, when an external register(pull up) is placed, is it more susceptible to noise than if there is no resistor on the outside?
Thanks,
Sam Lee
