Automotive 3-Channel Linear LED Driver with Analog and PWM Dimming

SGM3778Q.PDF

The SGM3778Q is a 3-channel linear LED driver with a wide 5V to 40V input voltage range.

The device provides both analog diming and PWM dimming methods to modulate LED current independently. Adjusting the REF pin resistor to set the regulated LED current and adjusting the PWMx input to achieve PWM dimming. The individual PWM control input for each channel features more application flexibility.

The SGM3778Q supports 1-to-3 LEDs in each channel with up to 150mA LED current. Paralleling the three outputs can provide up to 450mA LED current.

The SGM3778Q provides full kinds of protections, including short-circuit protection, single-LED short protection, open load protection, short-to-battery protection and thermal shutdown. When a fault occurs, the nFAULT and/or nFAULT_S pin report/s the fault status to MCU.

Besides the thermal shutdown protection, SGM3778Q provides a programmable thermal foldback feature through TEMP pin to reduce power dissipation at high junction temperature.

The device is AEC-Q100 qualified (Automotive Electronics Council (AEC) standard Q100 Grade 1) and it is suitable for automotive applications.

The SGM3778Q is available in a Green TSSOP-16 (Exposed Pad) package.
