Texas Instruments · Power Distribution Switches · WQFN-16-EP(3x3)
TPS2540ARTER from Texas Instruments, in a WQFN-16-EP(3x3). 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 | IN | power_in | Power-switch input voltage (4.5 V to 5.5 V recommended); connect a 0.1-µF or greater ceramic capacitor from IN to GND as close to the device as possible. |
| 2 | DM_OUT | bidirectional | D- data line to the USB host controller. |
| 3 | DP_OUT | bidirectional | D+ data line to the USB host controller. |
| 4 | ILIM_SEL | input | Logic-level input that dynamically changes the power-switch current-limit threshold; logic LO selects ILIM0, logic HI selects ILIM1. |
| 5 | EN | input | Logic-level control input for turning the power switch and signal switches on/off; when EN is low the device is disabled and the signal and power switches are OFF. |
| 6 | CTL1 | input | Logic-level control input for controlling the charging mode and the signal switches. |
| 7 | CTL2 | input | Logic-level control input for controlling the charging mode and the signal switches. |
| 8 | CTL3 | input | Logic-level control input for controlling the charging mode and the signal switches; on the TPS2540/40A the CTL1-3 '000' configuration forces a discharge of the OUT capacitor. |
| 9 | N/C | unconnected | No connect pin; can be grounded or left floating. |
| 10 | DP_IN | bidirectional | D+ data line to the connector, input/output used for handshaking with portable equipment. |
| 11 | DM_IN | bidirectional | D- data line to the connector, input/output used for handshaking with portable equipment. |
| 12 | OUT | power_out | Power-switch output. |
| 13 | FAULT | output | Active-low open-drain output, asserted during over-temperature or current-limit conditions. |
| 14 | GND | power_in | Ground connection; should be connected externally to the PowerPAD. |
| 15 | ILIM1 | passive | External resistor to GND sets the current-limit threshold when ILIM_SEL is HI; recommended 16.9 kΩ ≤ RILIM ≤ 750 kΩ. |
| 16 | ILIM0 | passive | External resistor to GND sets the current-limit threshold when ILIM_SEL is LO; recommended 16.9 kΩ ≤ RILIM ≤ 750 kΩ. |
| 17 | PowerPAD | power_in | Exposed thermal pad internally connected to GND, used to heat-sink the part to the circuit board traces; connect to the GND plane. |
