ETA7017CSE from etasolution, in a WLCSP0.87x0.87-4. 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 |
|---|---|---|---|
| A1 | OUT | power_out | Switch output; connect a 1uF ceramic capacitor from OUT to GND as close as possible to the IC. |
| B1 | GND | power_in | IC ground. |
| A2 | IN | power_in | Switch input (operating range 1.4V to 5.5V); connect a 1uF ceramic capacitor from IN to GND as close as possible to the IC. |
| B2 | EN | input | Enable input; logic high turns on the power switch, and the part has an internal 10 Mohm EN pull-down resistor. |

Package_CSP:WLCSP-4_0.89x0.89mm_Layout2x2_P0.5mm - 3D model: WLCSP0.87x0.87-4, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.35 mm nominal DSBGA height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
