Hello TI,
Please kindly help to check the questions about PGOOD of LM61460AASQRJRRQ1 below, thank you.
Q1: In the SNVSB70F datasheet (June 2021, pg. 35), it states that VCC can serve as a pull-up source with a 100kΩ pull-up resistor. In our project, due to an internal pull-down resistor (4.7kΩ) in the MCU, we plan to change the PGOOD pull-up resistor from 100kΩ to 4.7kΩ to meet the MCU’s VIH specification. Could you confirm if using a 4.7kΩ pull-up resistor with VCC as the pull-up source is acceptable?
Q2: Regarding the 100kΩ pull-up resistor, could you advise on the acceptable resistance range? Additionally, are there any other considerations I should be aware of? Thank you.
