| CN5501 |
| High-Voltage, Linear High-Brightness LED Driver IC |
|
| General Description： |
 |
| The CN5501 current regulator operates from a 4V to 32V input voltage range and delivers up to a total of 1A to one or |
| more strings of high-brightness LEDs.The output current of the CN5501 is adjusted by using an external current-sense |
| resistor in series with the LEDs. An enable input allows wide-range “pulsed” dimming. The CN5501 is well suited for |
| applications requiring high-voltage input and is able to withstand automotive load-dump events up to 32V. |
| LED short and open protection. An on-chip power MOSFET minimizes external components while providing ±5% |
| output current accuracy.Also an EQ pin is adopted for equalizing LED current among multiple CN5501 used in |
| parallel.Additional features include a 5V regulated output and thermal regulation, etc. |
| The CN5501 is available in a thermally enhanced 8-pin SOP package and 8-pin DFN package. |
