Pin Descriptions
Pin
Name
Function
1
NC
Not internally connected. Leave pin open.
2
VGHM
Output of GPM circuit. This output directly drives the supply for the gate driver circuits.
3
VFLK
Determines when the TFT LCD is on or off. This is controlled by the timing controller in
the LCD module.
4
VDPM
VDPM pin is the enable signal for the GPM block. Pulling this pin high enables the GPM
while pulling this pin low disables it. VDPM is used for timing sequence control.
5V
DD
Reference input for gate pulse modulation (GPM) circuit. The voltage at V
DD is used to set
the lower VGHM voltage.
6AV
IN
Op-Amp analog power input.
7
OUT
Output of the Op-Amp.
8
NEG
Negative input terminal of the Op-Amp.
9
POS
Positive input terminal of the Op-Amp.
10
AGND
Analog ground for the step-up regulator, LDO, and Op-Amp. Connect directly to DAP and
PGND beneath the device.
11
NC
Not internally connected. Leave pin open.
12
NC
Not internally connected. Leave pin open.
