NCA9511-DMSR from NOVOSENSE, in a MSOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | EN | input | Active-high chip enable pin; low sets shutdown mode, disables rise-time accelerators and pre-charge, drives READY low, and isolates IN/OUT pairs. |
| 2 | SCLOUT | output | Serial clock output connected to the SCL bus on the card side. |
| 3 | SCLIN | input | Serial clock input connected to the SCL bus on the backplane side. |
| 4 | GND | power_in | Supply ground. |
| 5 | READY | output | Open-drain connection indicator output; high when EN is high and buses are connected, low when EN is low or during startup. |
| 6 | SDAIN | input | Serial data input connected to the SDA bus on the backplane side. |
| 7 | SDAOUT | output | Serial data output connected to the SDA bus on the card side. |
| 8 | VCC | power_in | Main power supply input, 2.7-5.5 V; place 0.01 μF bypass capacitor and pull-up resistors on SDA/SCL lines to this supply. |
