Hi,
Our customer has some questions about DS100MB203.
Q1.
Regarding the RXDET(RX-Detect), how do they work? If we set INPUT_EN=1, what is the function of RXDET ?
Q2,
Regarding the Short Circuit Protection, how do they work?
Q3,
When SMBUS Slave mode is selected, how should we handle for EQ_D0,EQ_D1 pins ?
Q4,
Is 『RESET_b』 active low ? I believe RESET pin name is wrong.
Best Regards,
kato
Kato-san,
Q1. Regarding the RXDET(RX-Detect), how do they work? If we set INPUT_EN=1, what is the function of RXDET?
Ans: With INPUT_EN=1, the RXDET function is disabled. The input termination will always be active when INPUT_EN=1 and the device is powered on.
Q2. Regarding the Short Circuit Protection, how do they work?
Ans: The Short Circuit Protection is a current sense in the output circuit. It will turn the output "off" if it detects a situation which is demanding excessive current.
Q3. When SMBUS Slave mode is selected, how should we handle for EQ_D0,EQ_D1 pins?
Ans: These pins are not defined in the SMBus Slave mode. They can be left floating, no need to pull high/low.
Q4. Is RESET# active low? I believe RESET pin name is wrong.
Ans: The truth table for pin 52 is correct. This pin name should not have a line or bar over the name. The signal is designed to Enable/Disable the device. Enable = 0 and Disable = 1.
