TPS24770RGER
Texas Instruments · Supervisor And Reset ICs · VQFN-24-EP(4x4)
TPS24770RGER from Texas Instruments, in a VQFN-24-EP(4x4). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | NC | unconnected | No connect pin; tie to ground or leave floating. |
| 2 | ENHS | input | Active-high enable input of Hot Swap; a logic input that connects to a resistor divider. |
| 3 | NC | unconnected | No connect pin; tie to ground or leave floating. |
| 4 | FLTb | output | Active-low, open-drain output that indicates various faults. |
| 5 | PGHS | output | Active-high, open-drain power-good indicator output. |
| 6 | NC | unconnected | No connect pin; tie to ground or leave floating. |
| 7 | TINR | bidirectional | Inrush timer that runs during start-up when the part is in current limit or power limit. |
| 8 | TFLT | bidirectional | Fault timer that runs during regular operation when an overcurrent condition is present. |
| 9 | OV | input | Overvoltage comparator input that connects to a resistor divider; HGATE is pulled low when OV exceeds the threshold, and it should be connected to ground when not used. |
| 10 | GND | power_in | Ground. |
| 11 | PLIM | input | Power-limit programming pin; a resistor from this pin to GND sets the maximum power dissipation for the Hot Swap FET, and a 4.99 kΩ resistor disables 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, ranging from 0 V to 3.0 V. |
| 14 | VDD | power_in | Power supply pin; recommended operating input voltage range is 2.5 V to 18 V. |
| 15 | SET | input | Current-limit programming set pin; a resistor connects from the positive terminal of the sensing resistor to SET. |
| 16 | FSTP | input | Fast-trip programming set pin for Hot Swap; a resistor connects from the positive terminal of RSNS to FSTP. |
| 17 | SENM | input | Current-sensing input for the sense resistor, connected directly to the negative terminal of the sense resistor. |
| 18 | HGATE | output | Gate driver output for the external Hot Swap MOSFET. |
| 19 | OUTH | input | Output voltage sensor for monitoring the Hot Swap MOSFET power; connects to the source terminal of the Hot Swap N-channel MOSFET. |
| 20 | NC | unconnected | No connect pin; tie to ground or leave floating. |
| 21 | NC | unconnected | No connect pin; tie to ground or leave floating. |
| 22 | NC | unconnected | No connect pin; tie to ground or leave floating. |
| 23 | NC | unconnected | No connect pin; tie to ground or leave floating. |
| 24 | NC | unconnected | No connect pin; tie to ground or leave floating. |
| 25 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
