MAX17079集成电路（IC）的电源管理-专用规格书PDF中文资料

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 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.
