MIC94163YCS-TR

Microchip Tech · Power Management Specialized - PMIC · WLCSP-6(1x1.5)

MIC94163YCS-TR from Microchip Tech, in a WLCSP-6(1x1.5). 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
A1 VOUT power_out Source of the N-channel MOSFET, the switched output; tied internally with B1.
B1 VOUT power_out Source of the N-channel MOSFET, the switched output; tied internally with A1.
C1 GND power_in Ground.
A2 VIN power_in Input supply (drain of the N-channel MOSFET), operating range 1.7V to 5.5V; tied internally with B2.
B2 VIN power_in Input supply (drain of the N-channel MOSFET), operating range 1.7V to 5.5V; tied internally with A2.
C2 EN input Active-high enable input with internal 2 MΩ pull-down resistor; output is off if left floating, and the MIC94163 turns on above 1.2V (enable up to 5.5V, not limited by VIN).

CAD (KiCad official)

  • Symbol: MIC94163YCS-TR
  • Footprint: Package_CSP:WLCSP-6_1.4x1.0mm_P0.4mm
  • 3D model: WLCSP-6(1x1.5), 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)
  • 3D model files: mic94163ycs-tr-etched.step / mic94163ycs-tr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mic94163ycs-tr.step / mic94163ycs-tr.glb are the bare package body.
