Infineon · AC-DC Controllers and Regulators · SOT-223-4

ITS4141N from Infineon, in a SOT-223-4. 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 OUT power_out Output to the load. High-side switched output from Vbb; on-state resistance 200 mΩ (typ 150 mΩ). Clamped for inductive-load switch-off (VON(CL) 62-68 V) and includes a body/inverse diode to Vbb for reverse-battery current.
2 GND power_in Logic (signal) ground reference. Operating current IGND ≈ 1 mA (max 1.6 mA). A 150 Ω series GND resistor is recommended for reverse-battery protection and to limit GND current when Vbb exceeds Vbb(AZ) = 47 V.
3 IN input CMOS-compatible logic input; a logic-high signal activates the high-side switch. VIN(T+) ≤ 3.0 V turn-on threshold, VIN(T-) ≥ 1.82 V turn-off threshold, 0.2 V hysteresis. Internal ~3 kΩ input resistor (1.5-5 kΩ) with ESD zener clamps to Vbb and GND; input current ±5 mA max.
4 Vbb power_in Positive battery/supply pin. Operating range 12-45 V (absolute max 48 V). Overvoltage protection Vbb(AZ) = 47 V. Undervoltage shutdown 7-10.5 V with ~0.5 V hysteresis; standby current ≈ 10 µA (max 25 µA at 85 °C) when IN is low.
