EMC2302-2-AIZL-TR from Microchip Tech, in a MSOP-10. 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 | SMDATA | bidirectional | Open-drain bidirectional SMBus data pin (5V tolerant digital input/open-drain output) that requires an external pull-up resistor. |
| 2 | SMCLK | input | SMBus clock input (5V tolerant digital input) that requires an external pull-up resistor. |
| 3 | VDD | power_in | Input power supply pin for the device. |
| 4 | GND | power_in | Ground for the device. |
| 5 | PWM1 | output | Fan Speed Control 1 output, configurable as push-pull or open-drain PWM output. |
| 6 | TACH1 | input | Open-drain tachometer input (5V tolerant) for Fan Speed Control 1 feedback, requiring an external pull-up resistor. |
| 7 | PWM2 | output | Fan Speed Control 2 output, configurable as push-pull or open-drain PWM output. |
| 8 | TACH2 | input | Open-drain tachometer input (5V tolerant) for Fan Speed Control 2 feedback, requiring an external pull-up resistor. |
| 9 | CLK | bidirectional | Common 32.768 kHz external clock input for improved tach accuracy, or push-pull clock output to other fan controllers to synchronize Fan Speed Control. |
| 10 | ALERT | output | Active-low open-drain SMBus alert interrupt output (5V tolerant) indicating out-of-limit or error conditions, requiring an external pull-up resistor. |
