The MAX17135 is a complete power-management IC for E-paper displays that provides source- and gate-driver power supplies, a high-speed VCOM amplifier, and a temperature sensor.
The source-driver power supplies consist of a boost converter and an inverting buck-boost converter that generates +15V (up to +17V) and -15V (up to -17V), respectively. Both source-driver power supplies can deliver up to 200mA. The positive source-driver supply regulation voltage (VPOS) can be set either by using an I²C interface or by connecting an external resistor-divider. The negative source-driver supply voltage (VNEG) is always tightly regulated to -VPOS within ±50mV.
The gate-driver power supplies consist of regulated charge pumps that generate +22V (up to +40V) and -20V (up to -40V) and can deliver up to 20mA each.
The IC features a VCOM amplifier output whose output voltage is controlled by an internal 8-bit digital-to-analog converter (DAC). The DAC is programmable through an I²C interface and allows small-voltage-step sizes per DAC step.
The IC includes a temperature sensor that provides the ability to read the internal IC temperature and an external panel temperature with the use of an external temperature-sensing diode. Temperature output data is supplied through I²C.
The device is available in a space-saving, 32-pin TQFN package and is specified over the -40°C to
