MAX20067/MAX20067B

Automotive 3-Channel Display Bias IC with

VCOM Buffer, Level Shifter, and I C Interface

General Description

Benefits and Features

The MAX20067/MAX20067B are complete TFT bias solu-

tions for automotive applications. They include a current-

mode boost converter and two push-pull charge-pump dri-

vers.

● Versatile TFT Display Power Section

• Integrated Synchronous Boost Converter with

Output Voltages Up to 18V and High-power

(MAX20067) or Lower-power (MAX20067B)

Options

The ICs also include 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

• Integrated Charge-Pump Drivers for the VGON

(+32V, max) and VGOFF (-24V, min) Outputs

ICs can be used in stand-alone mode or through the I C

● Low EMI Operation

interface.

• Programmable Switching Frequencies of 440kHz or

2.2MHz

• Programmable Spread Spectrum

Comprehensive control functions are included using the

built-in I C interface, as well as diagnostics and monitor-

ing.

● Full Sequencing Flexibility Through I C, Along with

Preset Sequences Using SEQ Pin

● Extended Diagnostics Using I C Interface

The ICs are intended to operate with 2.7V to 5.5V sup-

plies.

• Undervoltage/Overvoltage on HVINP, VGON, and

VGOFF

• Overcurrent on AVDD

The MAX20067/MAX20067B are available in a 32-pin

TQFN package and operate in the -40°C to +105°C tem-

perature range.

• Temperature Warning

● Built-In Gate-Shading Circuit Controlled by CTL Input

● 8-Bit DAC-Controlled VCOM Buffer

● Robust

Applications

● Infotainment Displays

● Central Information Displays

● Instrument Clusters

• -40°C to +105°C Operating Temperature Range

• Internal Temperature Shutdown

• AEC-Q100 Qualified

● Compact 32-Pin (5mm x 5mm) TQFN Package
