TPS24741RGER 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 | CP | bidirectional | Connect a storage capacitor from CP to A for fast turn-on of the blocking gate. |
| 2 | ENHS | input | Active-high enable input of the hot-swap function; logic input that connects to a resistor divider. |
| 3 | ENOR | input | Active-high enable input of the ORing function; logic input that connects to a resistor divider. |
| 4 | FLTb | output | Active-low, open-drain output indicating various faults. |
| 5 | PGHS | output | Active-high, open-drain power-good indicator for the hot-swap function. |
| 6 | STAT | output | Output that is high when BGATE is ON. |
| 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 goes from regular operation to an over-current condition. |
| 9 | OV | input | Overvoltage comparator input that connects to a resistor divider; HGATE and BGATE are pulled low when OV exceeds the threshold, and it must be connected to ground when not used. |
| 10 | GND | power_in | Ground. |
| 11 | PLIM | input | Power-limiting programming pin; a resistor from this pin to GND sets the maximum power dissipation for the hot-swap FET. |
| 12 | IMON | bidirectional | Analog current monitor and load 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 of the device. |
| 15 | SET | input | Current-limit programming set pin for hot-swap; a resistor is connected from the positive terminal of the sensing resistor to SET. |
| 16 | FSTP | input | Fast-trip programming set pin for hot-swap; a resistor is connected from the positive terminal of the sensing resistor to FSTP. |
| 17 | SENM | input | Current-sensing input for the sensing resistor, directly connected to the negative terminal of the sensing resistor. |
| 18 | HGATE | output | Gate driver output for the external hot-swap MOSFET. |
| 19 | OUTH | input | Output voltage sensor for monitoring hot-swap MOSFET power; connects to the source terminal of the hot-swap N-channel MOSFET. |
| 20 | C | power_in | Voltage sense input connected to the OR MOSFET body-diode cathode (OR MOSFET drain in the typical configuration); also supplies power to the ORing block under certain biasing conditions. |
| 21 | RVSNP | input | Positive input of the reverse voltage comparator; connect a resistor from RVSNP to C to set the reverse voltage trip point of the blocking FET. |
| 22 | BGATE | output | Gate driver output that connects to the gate of the external OR MOSFET to control it so it emulates a low forward-voltage diode. |
| 23 | A | power_in | Voltage sense input connected to the OR MOSFET body-diode anode (OR MOSFET source in the typical configuration); also supplies power to the ORing block under certain biasing conditions. |
| 24 | RVSNM | input | Negative input of the reverse voltage comparator. |
| 25 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
