Pin Descriptions
PIN
FUNCTION
OUT
Adjustable Sink Current Output Pin. The current sinks into the OUT pin is equal to the DAC setting times the maximum adjustable sink
current divided by 128. See SET pin function description for the maxim adjustable sink current setting.
AVDD
High-Voltage Analog Supply. Connects to top of external resistor divider to determine the VCOM voltage. Typically 10V to 20V. Bypass
to GND with 0.1μF de-coupling capacitor.
N/C
No Connect. Not internally connected.
GND
Ground connection.
V
DD
ISL45042A power supply input. Bypass to GND with 0.1μF de-coupling capacitor.
CTL
Internal Counter Up/Down Control and Internal EEPROM Programming Control Input. If CE is high, a mid-to-low transition increments
the 7-bit counter, raising the DAC setting, increasing the OUT sink current, and lowering the divider voltage at OUT. A mid-to-high
transition decrements the 7-bit counter, lowering the DAC setting, decreasing the OUT sink current, and increasing the divider voltage
at OUT. Applying 4.9V and above with appropriately arranged timing will overwrite EEPROM with the contents in the 7-bit counter.
See EEPROM Programming section for details.
CE
Counter Enable Pin. Connect CE to V
DD
to enable adjustment of the output sink current. Float or connect CE to GND to prevent
further adjustment or programming (note: the CE pin has an internal pull down resistor).
SET
Maximum Sink Current Adjustment Point. Connect a resistor from the SET pin to GND to set the maximum adjustable sink current of
the OUT pin. The maximum adjustable sink current is equal to (AVDD/20) divided by RSET. The maximum set current has to be less
than 120
μ
A.
