SNLA492 September 2025 TDP2004-Q1
For the TDP2004-Q1, there are five 5-level input pins:
These 5-level inputs use an external resistor to help set the five valid levels as shown in Table 2-1.
| Level | Setting |
|---|---|
| L0 | 1k? to GND |
| L1 | 8.25k? to GND |
| L2 | 24.9k? to GND |
| L3 | 75k? to GND |
| L4 | Floating |
The TDP2004-Q1 can be configured in three different ways through the MODE pin:
| Level | Configuration |
|---|---|
| L0 | Pin-strap mode |
| L1 | SMBus/ I2C primary mode |
| L2 | SMBus/ I2C secondary mode |
| L3 and L4 | Reserved |
Pin strap mode – The TDP2004-Q1 control configuration is done solely by strap pins.
SMBus/I2C Primary mode – The TDP2004-Q1 control configuration is automatically read from an external EEPROM.
SMBus/I2C Secondary mode – The TDP2004-Q1 control configuration is controlled through an external Serial Management Bus (SMBus/I2C)
