TPS259571DSGT

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

TPS259571DSGT from Texas Instruments, in a WSON-8-EP(2x2). Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 dVdt input Capacitor from this pin to GND sets the output turn-on slew rate (maximum voltage 2.5 V); leave floating for fastest turn-on.
2 EN/UVLO input Active high enable input with adjustable UVLO threshold (1.03-1.27 V) via external resistor divider; maximum voltage 6 V.
3 IN power_in Power supply input (2.7-18 V recommended, 20 V absolute maximum).
4 IN power_in Power supply input (2.7-18 V recommended, 20 V absolute maximum).
5 OUT power_out Power supply output (0 to VIN + 0.3 V).
6 FLT tri_state Open-drain fault indicator output pulled low when a fault is detected; requires external pull-up resistor, maximum voltage 6 V.
7 ILM bidirectional Programmable current limit via external resistor to GND (487-5000 Ω range) and load current monitor output with pin voltage reflecting load current.
8 GND power_in Ground and power return.
9 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
