Hi,
I am designing a board with a MPM82504 module used as follows:
- OUT1 + OUT2 : 0.95V @ 50A
- OUT3 : 1.5V @ 25A
- OUT4 : 1.2V @ 25A
To do that
- the voltages are set with external resistive dividers: VOSNSn- tied to ground, resistor between VOSNSn- and VOSNSn+, resistor between VOSNSn+ and VOUTn
- CTRL1 and CTRL2 are tied together and connected to 3.3V through a pull-up, CTRL3 and SET4 are separately connected to 3.3V through pull-ups
- SET1 and SET2 are tied together, while SET3 and SET4 are left floating
- SUM1 and SUM2 are tied together, while SUM3 and SUM4 are left floating
- PS1 is tied to ground, while PS2, PS3 and PS4 are left floating
- TAKE1 is connected to PASS2 and 3.3V through a pull-up, PASS1 is connected to TAKE2, TAKE3 is connected to PASS3 and 3.3V through a pull-up, TAKE4 is connected to PASS4 and 3.3V through a pull-up
- ADDR1 and ADDR2 are tied together and connected to ground through a 4.99k resistor, ADDR3 is connected to ground through a 15k resistor, ADDR4 is connected to ground through a 24.9k resistor
Now, I need to be sure it is going to work with a MPM82504-0000 part. If the device is properly configured by outside components, what is the purpose of the configuration code, 0000 is this case? Do I need a specific configuration code?
Kind regards,
Ralph
