Pin Description
Pin Number
Pin Name
Pin Function
6, 31
5VINA, 5VINB
5V Supply Power and Sense Inputs [A/B]: Two pins are provided for Kelvin
connection (one for each slot). Pin 6 is the Kelvin sense connection to the
supply side of the sense resistor for 5V Slot A. Pin 31 is the Kelvin sense
connection to the supply side of the sense resistor for 5V Slot B. These two pins
must ultimately connect to each other within 10cm. An undervoltage lockout
circuit (UVLO) prevents the switches from turning on while this input is less than
its lockout threshold.
12, 25
3VINA, 3VINB
3.3V Supply Power and Sense Inputs [A/B]: Two pins are provided for Kelvin
connection (one for each slot). Pin 12 is the Kelvin sense connection to the
supply side of the sense resistor for 3V Slot A. Pin 25 is the Kelvin sense
connection to the supply side of the sense resistor for 3V Slot B. These two pins
must ultimately connect to each other within 10cm. An undervoltage lockout
circuit (UVLO) prevents the switches from turning on while this input is less than
its lockout threshold.
5, 32
12VIN 2 pins
+12V Supply Input: An undervoltage lockout circuit prevents the switches from
turning on while this input is less than its lockout threshold. Both pins must be
tied together at the chip.
17, 18
12VMIN 2 pins
12V Supply Input: An undervoltage lockout circuit prevents the switches from
turning on while this input is less than its lockout threshold. Both pins must be
tied together at the chip.
10, 27
12VOUTA, 12VOUTB
12V output [A/B]
19, 20
12MVOUTA, 12MVOUTB 12V output [A/B]
3, 34
12VSLEWA, 12VSLEWB 12V Slew Rate Control [A/B]: Connect capacitors between these pins and
ground to set output slew rates of the +12V and -12V supplies.
