4-Level or 2-Level Logic to High-Voltage Level Shifter for TFT LCD TV Display
General Description
The MAX17079 is a 7-channel logic-level input to high-
voltage output level shifter. Each channel has two
inputs plus a shared enable input. Each channel has
two outputs, which can be set to five output levels. Two
outputs are complementary to each other. The five out-
put levels are set by five supply rails that are common
to all 14 outputs.
The five supply rails include a typical TFT VCOM rail.
Two upper rails are always greater than VCOM, with
VH1 always greater than VH2. The two lower rails are
always less than VCOM, with VL1 always less than VL2.
Other supply rails are VLS (the typical TFT AVDD sup-
ply) and VCC (the logic supply). The MAX17079 can
also be configured as a two-level voltage shifter.
When EN is low, all 14 outputs connect to VCOM, and
when EN is high, the outputs are determined by their
inputs. The logic inputs are driven by the timing con-
troller. The output switches are typically 3Ωwith low
propagation delays and fast rise times. The MAX17079
has a minimum dead time to prevent shoot-through cur-
rents between supplies. The MAX17079 has thermal
shutdown to protect against overheating, VCC under-
voltage lockout (UVLO), and VLSUVLO.
The MAX17079 is in a 40-pin, 6mm x 6mm, thin QFN
package, with exposed pad and a maximum height of
0.8mm.
