MY9868A
MY9868A is 16-Channel Constant Current LED Driver manufactured by MY-Semi.
- Part of the MY9868A-MY comparator family.
- Part of the MY9868A-MY comparator family.
Description
The MY9868A, 16-channel c o n s t a n t c u r r e n t LED driver with double latch display technology, is suitable for any static and dynamic applications. The distinctive double latch technology enhances the visual refresh rate and low grayscale uniformity by increasing LED utilization rate. And the ghost image abatement is designed to eliminate ghosting of multiplexing LED modules due to parasitic capacitors.
The device operates over a 3.3V to 5V input voltage range (±10%) and provides 1 6 open-drain constant current sinking outputs that are rated to 1 7 V and delivers up to 45m A of high accuracy current to each string of LED. The current at each output is programmable by means of an external current-sensing resistor.
The MY9868A’s on-board pass elements minimize the need for external ponents, while at the same time, providing ±3% c h a n n e l current accuracy and ±4% c h i p current accuracy. Additional features include a ±0.1% regulated output current capability. The MY9868A is available in a 24-pin SSOP/QFN package and specified over the -40°C to +85°C ambient temperature range.
