The MAX1621EEE is a specialized power management integrated circuit designed for LCD backplane bias voltage generation. It converts battery voltages from 1.8V to 20V into positive or negative LCD bias voltages.
This IC features a 32-level internal DAC for digital software control of the bias voltage, and the MAX1621 variant includes an SMBus serial interface. It can automatically disable the backplane bias voltage when the display logic voltage is removed, protecting the display.
The MAX1621EEE operates with a low current consumption of 150µA, typically from a display logic supply of 3.0V to 5.5V. It is designed for use in applications such as notebook computers, palmtop computers, personal digital assistants, and portable data-collection terminals.
Packaged in an ultra-small 16-QSOP, the MAX1621EEE requires minimal PC board area and uses small, low-profile external components. It is suitable for surface mount applications and operates over a temperature range of -40°C to +85°C.
