TPS24742RGER 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, with a recommended CP capacitance of 1 nF to 1000 nF. |
| 2 | ENHS | input | Active-high enable input for the hot-swap controller, a logic input intended to connect to a resistor divider. |
| 3 | ENOR | input | Active-high enable input for the ORing controller, a logic input intended to connect to a resistor divider. |
| 4 | FLTb | output | Active-low open-drain output indicating various faults, with sink current limited to 0 to 2 mA and input/output voltage up to 18 V. |
| 5 | PGHS | output | Active-high open-drain power-good indicator for the hot-swap output, with sink current limited to 0 to 2 mA. |
| 6 | STAT | output | Status output that is high when BGATE is ON, with sink current limited to 0 to 2 mA. |
| 7 | TINR | bidirectional | Inrush timer pin that runs during start-up when the part is in current limit or power limit, with an external capacitor of 1 nF. |
| 8 | TFLT | bidirectional | Fault timer pin that runs when the device goes from regular operation to an over-current condition, with an external capacitor of 1 nF. |
| 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 should be connected to ground when not used. |
| 10 | GND | power_in | Ground reference for the device. |
| 11 | PLIM | input | Power-limit programming pin where a resistor from this pin to GND sets the maximum power dissipation for the hot-swap FET, with resistance of 4.99 kΩ to 500 kΩ. |
| 12 | IMON | bidirectional | Analog current monitor and load current limit program point, with RIMON connected to ground and a recommended resistance of 1 kΩ to 6 kΩ. |
| 13 | IMONBUF | output | Voltage output proportional to the load current, ranging from 0 V to 3.0 V, with a recommended maximum external capacitance of 100 pF. |
| 14 | VDD | power_in | Power supply input, with a recommended operating range of 2.5 V to 18 V and an absolute maximum of 30 V. |
| 15 | SET | input | Current-limit programming set pin for the hot-swap, where a resistor connects from the positive terminal of the sensing resistor to SET, with a recommended resistance of 10 Ω to 400 Ω; do not apply voltage to this pin. |
| 16 | FSTP | input | Fast-trip programming set pin for the hot-swap, where a resistor connects from the positive terminal of the sensing resistor to FSTP, with a recommended resistance of 10 Ω to 4000 Ω. |
| 17 | SENM | input | Current-sensing input that connects directly to the negative terminal of the sensing resistor, with a recommended operating voltage of 2.5 V to 18 V. |
| 18 | HGATE | output | Gate driver output for the external hot-swap MOSFET, with a maximum HGATE-to-OUTH voltage of 15 V and an external capacitance of up to 1 µF in series with at least 1 kΩ. |
| 19 | OUTH | input | Output voltage sensor for monitoring hot-swap MOSFET power, connecting to the source terminal of the hot-swap N-channel MOSFET, with a recommended input voltage of 0 V to 18 V. |
| 20 | C | power_in | Voltage sense input that connects to the OR MOSFET drain and supplies power to the ORing block under certain biasing conditions, with an absolute maximum of 30 V. |
| 21 | RVSNP | input | Positive input of the reverse voltage comparator, where a resistor from RVSNP to C sets the reverse voltage trip point, with a recommended resistance of 10 Ω to 1000 Ω and capacitance of 1 nF to 1000 nF. |
| 22 | BGATE | output | Gate drive output that controls the external OR MOSFET to emulate a low forward-voltage diode, with an absolute maximum of 40 V (12 V relative to A). |
| 23 | A | power_in | Voltage sense input that connects to the OR MOSFET source and supplies power to the ORing block under certain biasing conditions, with an absolute maximum of 30 V. |
| 24 | RVSNM | input | Negative input of the reverse voltage comparator, with a recommended operating voltage of 0.7 V to 18 V. |
| 25 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
