SIP32429DN-T1-GE4

Vishay · AC-DC Controllers and Regulators · TDFN-10-EP(3x3)

SIP32429DN-T1-GE4 from Vishay, in a TDFN-10-EP(3x3). 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 input. 6 V to 28 V supply and switch input. Tie to pin 2 (both VIN pins connect to the switch input node); bypass with CIN to GND.
2 VIN power_in Power input. Second VIN pad, tied internally to pin 1. 6 V to 28 V operating range (30 V absolute max).
3 SS input Soft-Start pin. Connect a capacitor CSS from SS to GND to program the soft-start (slew rate) time. Leave SS open to select the default 400 µs turn-on. Internally driven by a ~4.5 µA constant current source.
4 EN input Enable input. Logic high enables the switch (VENH ≥ 1.5 V), logic low disables it (VENL ≤ 0.6 V). Internal 2.5 MΩ pull-down. Absolute max 6 V.
5 ILIM input Current limit setting pin. Connect an RSET resistor from ILIM to GND to program the over-current threshold (0.75 A to 3.5 A range; e.g. RSET = 4.1 kΩ → ILIM ≈ 1.5 A typ).
6 GND power_in Device ground reference for logic, control, and CSS/RSET networks.
7 /PG output Active-low Power Good open-drain output. Pulls low when VOUT reaches ≥ 90 % of VIN (3 % hysteresis). Requires an external pull-up (biasable up to 28 V). ISINK = 1 mA → VOL < 0.1 V.
8 /FLG output Active-low fault condition flag, open-drain. Asserts low on over-current (after 4-6 ms blanking) or over-temperature events. Requires external pull-up (biasable up to 28 V).
9 VOUT power_out Switch output. Second VOUT pad, tied internally to pin 10. Delivers the switched VIN to the load through a 56 mΩ (typ) high-side PMOS.
10 VOUT power_out Switch output. Tie to pin 9. Bypass to GND with COUT. Supports up to 4.5 A continuous switch current.
11 EP passive Central exposed thermal pad. Connect to GND plane for thermal dissipation (θJA = 88 °C/W when soldered) or leave floating per datasheet allowance.
