LM95235DIMMX from Texas Instruments, in a VSSOP-8-0.65mm. 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 | VDD | power_in | Device power supply, 3.0 V to 3.6 V. Requires a 10 µF bypass capacitor in parallel with 0.1 µF and 100 pF, with the 100 pF placed closest to the pin. Typical supply current is 350 µA at a 1 Hz conversion rate. |
| 2 | D+ | passive | Positive analog input from the remote thermal diode (anode). Connects to the diode-connected transistor's base/collector (MMBT3904) or the D+ node of an on-die processor thermal diode. Route with D- as a tightly coupled differential pair; a 100 pF filter capacitor across D+/D- close to the LM95235 is recommended. |
| 3 | D- | passive | Negative analog input from the remote thermal diode (cathode/emitter). Provides the return path for the temperature-sensing bias currents; internally referenced but should not be tied directly to board ground - return to LM95235 GND through the analog input pair only. |
| 4 | T_CRIT | output | Critical-temperature comparator output. Open-drain, active-low; requires an external pull-up resistor (typ. 1.3 kΩ to 3.3 V). Asserted when either unmasked channel exceeds its programmed T_CRIT limit; typically used for system shutdown or fan control. |
| 5 | GND | power_in | Device ground reference for both digital and analog circuitry. |
| 6 | OS/A0 | bidirectional | Dual-function pin. Defaults after power-up as a three-level SMBus slave address input (A0): tie to VDD, GND, or to the mid-point of a resistor divider between VDD and GND to pick one of three slave addresses. When reprogrammed via the configuration register it becomes the OS (over-temperature shutdown) comparator output - active-low, open-drain, requiring an external pull-up. |
| 7 | SMBDAT | bidirectional | SMBus 2.0 serial data line (SMBus/I²C-compatible). Open-drain; requires an external pull-up resistor (typ. 1.3 kΩ to 3.3 V). Supports the SMBus TIMEOUT feature. |
| 8 | SMBCLK | input | SMBus 2.0 serial clock input (SMBus/I²C-compatible). Driven by the SMBus master; requires an external pull-up (typ. 1.3 kΩ to 3.3 V) on the bus. |
