TPS259540DSGR

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

TPS259540DSGR 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 input Analog input for setting output turn-on slew rate via capacitor to ground; leave floating for fastest turn-on slew rate.
2 EN/UVLO input Active-high enable input with adjustable undervoltage lockout threshold configured via resistor divider; do not leave floating.
3 IN power_in Power supply input pin; part of dual input configuration.
4 IN power_in Power supply input pin; part of dual input configuration.
5 OUT power_out Power output switch terminal for delivering load current.
6 FLT output Open-drain fault indicator output pulled low when fault is detected; requires external pull-up resistor.
7 ILM bidirectional Dual-function pin for output current limiting and monitoring via external resistor to ground; pin voltage provides load current indication; do not leave floating.
8 GND power_in Ground reference connection.
9 PAD passive Exposed pad (from the footprint; not named in the datasheet pin table).
