内容描述: [The TLD7002-16ES is a 16 channel device with integrated and protected output stages. It is designed to control LEDs with a current up to 76.5 mA as linear current sink (LCS). The power stages can be configured in parallel for higher load currents. Each individual power output stage is configured to a 6-bit current set value stored in the OTP. 16 independent and individual PWM configurations can be set. A high-speed lighting interface is used for device OTP programming, configuration, control and]

ERRN report  
The device is able to report a detected load fault with the ERRN pin.  
The open-drain ERRN pin sinks a pull-down current IERRN in ≤ tERRN when  
the device is in init OR fail-safe mode OR active mode AND  
a load fault OR internal fault OR warning has been detected AND  
the ERRN is enabled via the OTP  
Following diagnostic is disabled on OUT15, when it is used as ERRN feedback:  
min(VOUT) measurement  
open load detection  
single led short detection  
VFWD warning  
PWM duty cycle monitoring only for channel 15  
current monitor  
short between adjacent channels
