NOVOSENSE · Surge Protection Devices (SPDs) · MSOP-8

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.
