MIC4605-2YMT-TR from Microchip Tech, in a TDFN-10-EP(2.5x2.5). 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 | EN | input | Enable input: a logic high (VIH min 2.2 V) gives normal operation, and a logic low (VIL max 0.8 V) puts the device into Shutdown mode. |
| 2 | VDD | power_in | Input supply for the gate drivers, operating range 5.5 V to 16 V; decouple to VSS with a >0.1 µF capacitor. |
| 3 | HB | power_in | High-side bootstrap supply; an external bootstrap capacitor is required across HB and HS, and an on-board bootstrap diode connects VDD to HB. |
| 4 | HO | output | High-side drive output; connect to the gate of the external high-side power MOSFET. |
| 5 | HS | passive | High-side drive reference; connect to the source of the external high-side MOSFET and to the bottom of the bootstrap capacitor, with an operating voltage of -0.3 V to +85 V. |
| 6 | PWM | input | Single PWM input (MIC4605-2 only) that drives the high-side and low-side outputs out of phase. |
| 7 | NC | unconnected | No connect; this pin is not connected internally. |
| 8 | VSS | power_in | Driver reference supply input, generally connected to the power ground of the external circuitry. |
| 9 | LO | output | Low-side drive output; connect to the gate of the external low-side power MOSFET. |
| 10 | NC | unconnected | No connect; this pin is not connected internally. |
| 11 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
