# TPS2413D

**Texas Instruments** · Power Distribution Switches · SOIC-8

TPS2413D from Texas Instruments, in a SOIC-8. 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 | VDD | power_in | Primary supply for the gate-drive charge pump and internal controls, which must be at least 3 V (VDD must exceed 3 V to meet the gate-drive specification) and may be higher or lower than the controlled bus voltage. |
| 2 | RSET | input | A resistor from this pin to GND (1.5 kΩ to open-ended range) programs the fast turnoff threshold, where leaving it open gives a slightly positive threshold and the TPS2413 must use a negative threshold; RSET voltage is limited to -0.3 V to 7 V. |
| 3 | RSVD | power_in | Reserved pin that must be connected to GND. |
| 4 | GND | power_in | Device ground that needs a low-impedance connection to the ground plane, since it carries several amperes of rapid discharge current when the external MOSFET turns off. |
| 5 | GATE | output | Drives the gate of the external N-channel MOSFET relative to A using the BYP supply, is pulled to GND by a fast discharge on turnoff, and is rated -0.3 V to 30 V with GATE above BYP limited to 0.3 V. |
| 6 | C | input | Voltage-sense input for the simulated diode cathode, connected to the MOSFET drain, with C allowed up to 18 V above A. |
| 7 | A | input | Voltage-sense input for the simulated diode anode, connected to the MOSFET source and Kelvin connected to it, which also serves as the reference for the charge-pump supply on BYP and is limited to 7.5 V above C. |
| 8 | BYP | bidirectional | Charge-pump output and gate-drive supply that needs a capacitor from BYP to A (2200 pF ceramic recommended), and shorting BYP to a voltage below A damages the device; BYP is rated -0.3 V to 30 V with BYP to A limited to 13 V. |
