RS2588CYF5 from Jiangsu RUNIC Tech, in a SOT23-5. 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 | VOUT | power_out | Switch output: the P-channel drain of the power switch, which typically connects to the load; VOUT may be forced above VIN when the switch is disabled. |
| 2 | GND | power_in | Ground; all device voltages are referenced to this pin, with absolute maximum voltages of -0.3 V to 6.0 V relative to GND. |
| 3 | FLAG | output | Active-low open-drain flag output that asserts on over-current or thermal shutdown, with over-current required to last longer than tD (13 ms typical) before FLAG asserts. |
| 4 | EN | input | Logic-level enable input, active high, with VIL maximum 0.4 V and VIH minimum 1.6 V at VIN = 2.5 V to 5.5 V; EN has an internal pull-down resistor. |
| 5 | VIN | power_in | Power supply input: the P-channel source of the power switch that also supplies the internal circuitry, operating from 2.5 V to 5.5 V with an absolute maximum of 6.0 V. |
