TPS259531DSGT
Texas Instruments · Surge Protection Devices (SPDs) · WSON-8-EP(2x2)
TPS259531DSGT from Texas Instruments, in a WSON-8-EP(2x2). 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 | dVdt | bidirectional | A capacitor from this pin to GND sets the output turn-on slew rate, and the pin must be left floating for the fastest slew rate; the pin voltage is limited to 2.5 V absolute maximum. |
| 2 | EN/UVLO | input | This is the active-high enable input for the TPS259531 (x1 variant) and a resistor divider can set the undervoltage lockout threshold; it must not be left floating and its recommended range is 0 V to 6 V (7 V absolute maximum). |
| 3 | IN | power_in | This is the power input, rated 2.7 V to 18 V recommended (20 V absolute maximum) for the TPS2595x0/1/3 variants. |
| 4 | IN | power_in | This is the power input (second IN pin, internally tied to pin 3), rated 2.7 V to 18 V recommended (20 V absolute maximum) for the TPS2595x0/1/3 variants. |
| 5 | OUT | power_out | This is the power output (switched output of the internal eFuse FET), with the output voltage limited to VIN + 0.3 V and an output pulse of at least -1.2 V for less than 1 µs. |
| 6 | FLT | output | This is an open-drain fault indicator that is pulled low when a fault is detected and requires an external pull-up resistor; it can sink up to 10 mA and its voltage is limited to 0 V to 6 V. |
| 7 | ILM | bidirectional | An external resistor from this pin to GND sets the output current limit (RILM 487 Ω to 5000 Ω for active current limiting), the pin voltage can monitor load current, and it must not be left floating. |
| 8 | GND | power_in | This is the device ground reference pin. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
