TPS259570DSGT

Texas Instruments · Surge Protection Devices (SPDs) · WSON-8-EP(2x2)

TPS259570DSGT 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 passive Output turn-on slew rate control pin; connect capacitor (up to 3300pF, 4V rated) to GND for desired slew rate, or leave floating for fastest slew rate (absolute maximum 2.5V).
2 EN/UVLO input Active-high enable input with adjustable undervoltage lockout (UVLO) threshold via external resistor divider network (operating range 0 to 6V, do not leave floating).
3 IN power_in Power supply input pin (operating range 2.7V to 18V, absolute maximum -0.3V to 20V).
4 IN power_in Power supply input pin (operating range 2.7V to 18V, absolute maximum -0.3V to 20V).
5 OUT power_out Power output pin; output voltage range 0V to VIN + 0.3V operating, absolute maximum -0.3V to VIN + 0.3V.
6 FLT tri_state Open-drain fault event indicator output pulled low when fault detected; requires external pull-up resistor (operating range 0 to 6V).
7 ILM passive Current limit and load monitoring pin; connect external resistor (487Ω to 5kΩ) to GND to set output current limit (0.5A to 4A range, ±7.5% accuracy), monitor load current via pin voltage (do not leave floating).
8 GND power_in Ground return for power and signal circuits.
9 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
