description
The MPT57202 is a CMOS integrated circuit designed to drive an LCD (liquid crystal display) for a dot matrix
STN (super twisted nematic). The outputs can be configured as one set of 160 output channels or as two sets
of 80 output channels. The duty cycle is over 1/400, and the output bias voltage range (VEE) is from 20 V to 42
V (45 V maximum).
The outputs can be configured as one set of 160 output channels or as 2 sets of 80 output channels. This
high-voltage CMOS SI gate device is available in a custom TAB (tape automated bonding) package.
