TPS2419DR 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 | RSET | input | Connect a resistor to ground to program the V(A-C) turn-off threshold; leaving RSET open gives a slightly positive turn-off threshold. |
| 2 | EN | input | Pull EN above 1.3 V to permit normal ORing operation, a low on EN holds GATE low, and EN should not be driven above its 5 V recommended maximum. |
| 3 | RSVD | power_in | Reserved pin that must be connected to GND. |
| 4 | GND | power_in | Device ground, which should have a low-impedance connection to the ground plane because it carries several amperes of discharge current when the external MOSFET turns off. |
| 5 | GATE | output | Drives the gate of the external N-channel MOSFET to emulate a low forward-voltage diode, driven positive with respect to A from BYP and pulled down strongly at turn-off. |
| 6 | C | input | Cathode voltage sense input and bias supply for the gate-drive charge pump; it must be at least 3 V for the MOSFET to be turned on, and the input range is 0 to 16.5 V. |
| 7 | A | input | Anode voltage sense input connected to the MOSFET source, and the reference for the charge-pump supply on BYP; the input range is 0 to 16.5 V. |
| 8 | BYP | bidirectional | Charge-pump output and positive supply for the internal comparators and GATE driver, requiring a capacitor to A (2200 pF ceramic recommended) and never to be shorted to a voltage below A. |
