TMI6240

TMI · Power Distribution Switches · SOT-23-5

TMI6240 from TMI, in a SOT-23-5. 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 VIN power_in Power supply input pin. 2.7 V to 18 V operating range (20 V abs max). Bypass with a ≥1 µF X5R/X7R ceramic capacitor placed close to the pin.
2 GND power_in Ground reference pin for the device.
3 EN input Active-high enable input. Drive high (V_EN > 1.0 V typ. rising threshold) to turn the internal MOSFET on; drive low (< 0.9 V typ. falling threshold) to enter micro-power shutdown and trigger output auto-discharge (~30 mA). Do not float. Abs max 20 V.
4 SS passive Soft-start programming pin. Connect a capacitor (C_SS) from this pin to GND to set the output rising slew rate / soft-start time (e.g. 1.1 ms at C_SS=4.7 nF, V_IN=12 V). Floating gives the default minimum soft-start time (~0.15 ms). Abs max 6.0 V.
5 VOUT power_out Switch output pin. Drain of the internal N-channel MOSFET (R_DS(on) ≈ 50 mΩ at V_IN=12 V). Delivers up to 3.5 A to the load; auto-discharged to GND (~30 mA) when EN is low. Abs max 20 V.
