Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | NC | unconnected | No connect. Tie to ground or leave floating. |
| 2 | ENHS | input | Active-high enable input of Hot Swap. Logic input connects to resistor divider. |
| 3 | NC | unconnected | No connect. Tie to ground or leave floating. |
| 4 | FLTb | output | Active-low, open-drain output indicating various faults. |
| 5 | PGHS | output | Active-high, open-drain power-good indicator. |
| 6 | NC | unconnected | No connect. Tie to ground or leave floating. |
| 7 | TINR | bidirectional | Inrush timer, which runs during the inrush operation (start-up) if the part is in current limit or power limit. |
| 8 | TFLT | bidirectional | Fault timer, which runs when the device is in regular operation and there is an overcurrent condition. |
| 9 | OV | input | Overvoltage comparator input connects to resistor divider; HGATE pulled low when OV exceeds threshold or connect to ground when not used. |
| 10 | GND | power_in | Ground. |
| 11 | PLIM | input | Power limit programming pin; resistor from this pin to GND sets maximum power dissipation for Hot Swap FET, or connect 4.99 kΩ resistor to disable power limit. |
| 12 | IMON | bidirectional | Analog monitor and current limit program point; connect RIMON to ground. |
| 13 | IMONBUF | output | Voltage output proportional to the load current with range 0V-3.0V. |
| 14 | VDD | power_in | Power Supply input, 2.5V to 18V. |
| 15 | SET | input | Current-limit programming set pin for Hot Swap; resistor connected from positive terminal of the sensing resistor. |
| 16 | FSTP | input | Fast trip programming set pin for Hot Swap; resistor connected from positive terminal of RSNS to FSTP. |
| 17 | SENM | input | Current-sensing input for the sense resistor; directly connects to the negative terminal of the sense resistor. |
| 18 | HGATE | output | Gate driver output for external Hot Swap MOSFET. |
| 19 | OUTH | input | Output voltage sensor for monitoring Hot Swap MOSFET's power; connects to the source terminal of the Hot Swap N channel MOSFET. |
| 20 | NC | unconnected | No connect. Tie to ground or leave floating. |
| 21 | NC | unconnected | No connect. Tie to ground or leave floating. |
| 22 | NC | unconnected | No connect. Tie to ground or leave floating. |
| 23 | NC | unconnected | No connect. Tie to ground or leave floating. |
| 24 | NC | unconnected | No connect. Tie to ground or leave floating. |
| 25 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
