The TPL0401B-10QDCKRQ1 from Texas Instruments is an automotive-qualified single-channel 128-tap digital potentiometer with 10kOhm end-to-end resistance and I2C interface. The device uses non-volatile EEPROM to store the wiper position, ensuring the last programmed setting is automatically restored at power-up without requiring re-initialization by the host controller. With 128 taps (7-bit resolution), the device provides fine-grained resistance adjustment suitable for calibration and trimming applications. The I2C interface at address 0x50 (with A0 pin selecting between two possible addresses) allows the wiper position to be read and written by any I2C master. The device operates from 2.7V to 5.5V supply and can handle wiper currents of +/-2.5mA. In potentiometer mode, the device functions as a three-terminal voltage divider with H, L, and W terminals; in rheostat mode (using only W and one terminal), the resistance is programmable from approximately 78 ohms (one tap) to 10kOhms (full scale). The temperature coefficient of 35ppm/C in rheostat mode ensures stable resistance over the automotive temperature range. AEC-Q100 Grade 1 qualification supports operation from -40 to +125C. The compact SC-70-6 package (2.0 x 1.25mm) minimizes board space, enabling digital trim in space-constrained automotive modules.

The TPL0401B-10QDCKRQ1 operates as a digitally controlled potentiometer with EEPROM memory. Key subsystems include: (1) Resistor Array – a polysilicon resistor string of 127 equal resistors (approximately 78 ohms each for 10kOhm total) connected between H and L terminals; each node between resistors is selectable by the wiper multiplexer; (2) Wiper Multiplexer – a CMOS switch matrix that connects the W (wiper) terminal to any of the 128 tap points along the resistor string; the selected tap position is determined by the 7-bit register value stored in the volatile wiper register; (3) I2C Interface – a standard-mode I2C slave interface accepts write commands (to change wiper position) and read commands (to read current wiper position) at the device address 0x50 or 0x54 (selected by A0 pin); the interface also provides access to the EEPROM control register for saving the wiper position; (4) Non-Volatile EEPROM – the wiper position can be stored in the EEPROM by writing a specific command sequence; at power-up, the EEPROM contents are automatically loaded into the volatile wiper register, restoring the last saved position; the EEPROM supports a minimum of 50,000 write cycles; (5) Power-On Reset – on initial power-up, the device loads the EEPROM-stored wiper position into the active register; this ensures a known, valid wiper position without requiring I2C communication from the host.

Pin Name Function
1 A0 I2C address select (connect to GND or VDD)
2 GND Ground
3 H High terminal of resistor (potentiometer mode)
4 L Low terminal of resistor (potentiometer mode)
5 W Wiper terminal (programmable tap point)
6 VDD Power supply (2.7V to 5.5V)
  • LCD contrast trim: adjust VCOM voltage for optimal display contrast, EEPROM retains setting across power cycles
  • Power supply margining: digitally adjust feedback divider for output voltage calibration in production test
  • Sensor offset calibration: trim bridge offset voltage to zero during manufacturing calibration
  • LED current set: adjust LED driver current set resistor digitally for brightness matching in automotive lighting
