MIC44F19YMME from Microchip Tech, in a MSOP-8-EP. 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 | OUT | output | Driver output; redundant OUT pin (paired with pin 8) that lowers driver impedance, swinging within 25 mV of VDD or ground and sourcing/sinking 6A peak. |
| 2 | VDD | power_in | Supply input, operating range 4.5V to 12.6V (absolute maximum +13V). |
| 3 | NC | unconnected | No connect. |
| 4 | IN | input | Logic input; for the MIC44F19 logic-high gives a low output and logic-low gives a high output (inverting), with a TTL-compatible threshold of about 1.7V (VIH) and 1.53V (VIL) typical. |
| 5 | EN/UVLO | input | Enable/undervoltage-lockout input: pulling it below the 1.4V typical enable threshold disables the driver (MIC44F19 output goes high), floating it enables the driver with the internal 4.2V UVLO, and a resistor divider can set a different UVLO threshold. |
| 6 | GND | power_in | Ground. |
| 7 | GND | power_in | Ground. |
| 8 | OUT | output | Driver output; redundant OUT pin (paired with pin 1) that lowers driver impedance, swinging within 25 mV of VDD or ground and sourcing/sinking 6A peak. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
