TLD7002-16ES
Multi-channel LED driver
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 diagnostic feedback.
