The MAX20067/MAX20067B are complete TFT bias solution for automotive applications. It includes a current-mode boost converter and two push-pull charge-pump drivers.

The IC also includes a gate-shading push-pull level shifter that can be used to improve display uniformity (when needed), and a DAC and VCOM buffer. All blocks on the IC can be used in stand-alone mode or through the I2C interface.

Comprehensive control functions are included using the built-in I2C interface, as well as diagnostics and monitoring.

The IC is intended to operate with 2.7V to 5.5V supplies.

The MAX20067/MAX20067B are available in a 32-pin TQFN package and operates in the -40°C to +105°C temperature range.

Product Detail

The MAX20067 evaluation kit (EV kit) is a fully assembled and tested surface-mount PCB that provides the voltages and features required for automotive thin-film transistor (TFT), liquid-crystal display (LCD) applications. The EV kit includes a synchronous boost converter, double-stage positive charge pump, double-stage negative charge pump, VCOM buffer, and gate-shading push-pull switch. The EV kit can operate from 2.7V to 5.5V input voltages and is optimized for automotive TFT-LCD applications. The EV kit can be configured to operate in stand-alone mode or in I2C mode. The boost converter is configured for a 12V output that provides at least 200mA. The positive-gate voltage regulator provides 16V output and the negative-gate voltage regulator provides -6V. The VCOM buffer provides an I2C-adjustable output voltage initially biased at 6V.

The EV kit provides an I2C interface that can operate in conjunction with the MINIQUSB+ adapter board or a third-party I2C master, such as a general-purpose microcontroller. The EV kit also includes Windows®-compatible software that provides a simple graphical user interface (GUI) for exercising the features of the IC. The EV system includes both the EV kit and the MINIQUSB+ adapter board.
