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]

Power shif  
The device can limit the internal power dissipation by balancing one load current branch with two power stages and  
an external resistance.  
The primary output channel OUTn and secondary output channel OUTn+1 provide the output current IOUT = IOUTn  
IOUTn+1, where IOUTn+1 linearly increases until VOUTPS_HI threshold is reached. If VOUTn > VOUTPS_HI then IOUT = IOUTn+1  
5.625 mA and IOUTn = 5.625 mA. The sum of IOUTn and IOUTn+1 remains constant while VOUTn rises.

The external resistance is connected to the secondary output channel.  
The primary and secondary output channels are defined according to following table:

The power shif threshold VOUTPS_HI is programmable by a 2-bit OTP register with 4 options as shown below with an  
accuracy of a aVOUT_PS per configuration step.
