General Description
The GR8210 is a high brightness LED driver with
the cascode topology that patented by Grenergy. A
high voltage power NMOSFET, BVDSS is 600V, as
the high side device and the power NMOSFET
inside the GR8210 as the low side device in this
cascode topology. A Zener voltage, was generated
by ST pin of the GR8210, turn on the high side
device all the time by connected to the gate terminal
of the high side device. The source terminal and the
drain terminal of the high side device are connected
to the DRN pin of the GR8210 and the input voltage
rail respectively to absorb the very large voltage
potential. The current peak value was decided by
the sensing resistor in the CS pin, the low side
device was turned off by the current peak detection
then delay a fixed off time that set by the resistor in
the RT pin of GR8210.
There are PWM and liner dimming in GR8210 to
adjust the LED brightness. In the abnormal
operation, the inner OTP function could protect the
IC damage.
