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 output 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 supply) 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 controller. The output switches are typically 3Ω with low propagation delays and fast rise times. The MAX17079 has a minimum dead time to prevent shoot-through currents between supplies. The MAX17079 has thermal shutdown to protect against overheating, VCC undervoltage lockout (UVLO), and VLS UVLO.
The MAX17079 is in a 40-pin, 6mm x 6mm, thin QFN package, with exposed pad and a maximum height of 0.8mm.
