# TPS2419PW

**Texas Instruments** · Monitors & Reset Circuits · TSSOP-8

TPS2419PW from Texas Instruments, in a TSSOP-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 turn-off threshold; leaving RSET open results in a slightly positive V(A-C) turn-off threshold. |
| 2 | EN | input | Pull EN above 1.3 V to permit normal ORing operation, and a low on EN holds GATE low; EN should not be driven above its recommended maximum voltage of 5 V. |
| 3 | RSVD | power_in | This pin must be connected to GND. |
| 4 | GND | power_in | Device ground; it should have a low-impedance connection to the ground plane. |
| 5 | GATE | output | Connect to the gate of the external N-channel MOSFET to control it so it emulates a low forward-voltage diode; the absolute maximum GATE voltage is -0.3 to 30 V. |
| 6 | C | input | Voltage sense input connected to the simulated diode cathode and the bias supply for the gate-drive charge pump; it must be 3 V or greater for the external MOSFET to be turned on, with a recommended input range of 0 to 16.5 V. |
| 7 | A | input | Voltage sense input connected to the simulated diode anode and the reference for the charge-pump bias on BYP; connect to the MOSFET source in the typical configuration. |
| 8 | BYP | bidirectional | Connect a capacitor from BYP to A to filter the gate drive supply, with a 2200-pF ceramic recommended; shorting BYP to a voltage below A damages the device. |
