TPS259530DSGT

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

TPS259530DSGT 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 should be left floating for the fastest turn-on slew rate.
2 EN/UVLO input Active high enable for the TPS259530 (x0 variant), where a resistor divider can set the undervoltage lockout threshold and the pin must not be left floating.
3 IN power_in Power input for the eFuse, specified at 2.7 V to 18 V with 20 V absolute maximum.
4 IN power_in Power input for the eFuse, specified at 2.7 V to 18 V with 20 V absolute maximum.
5 OUT power_out Power output of the eFuse, with continuous output current up to 4 A over the junction range of -40 to 125 °C.
6 FLT output Open-drain fault indicator that is pulled low when a fault is detected and requires an external pull-up resistor.
7 ILM bidirectional Dual-function pin where an external resistor to GND sets the output current limit (RILM of 487 Ω to 5000 Ω) and the pin voltage monitors load current; it must not be left floating.
8 GND power_in Ground reference pin for the device.
9 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
