Logic ground pins. Be sure to use all.
Unused
This pin is used to reset the IC’s built-in temperature monitoring circuit (TSD).
Rising edge of input signal re-enables outputs which had been forced to OFF.
The latched data as the setting is not reset.
Either in case of H- or L-level of this terminal can be operated TSD circuit.
Ground pin for output. Be sure to use all.
Logic power supply input pins. Be sure to use all.
LED drive output pins. Connect to cathode of LED.
Serial data input pin. Used for input of standard current adjustment data and dot
adjustment data
Serial data transfer clock input pin. Data is transferred at positive edge.
Serial data latch signal input pin. Data is held on positive edge.
Serial data selection pin. Either standard current adjustment data or dot adjustment data
may be selected.
Serial data output pin. The output data type is selected using SI SEL.
Input pins for parallel data. Inputs for all output adjustment data and PWM data
Input pin for parallel data transfer clock. Data is transferred on positive edge.
Input pin for parallel data latch signal. Data is held on positive edge.
Parallel data selection pin. Either total dot adjustment data or PWM data may be selected.
Output pin for parallel data. The output data type is selected using PI SEL.
Control pin for parallel data output PO DATA. PI DATA is out on input of an H-level signal.
PI DATA is set to High-impedance by input of an L-level signal.
PWM circuit control signal input pin. Output is turn OFF by input of an H-level signal. PWM
output is initiated by input of an L-level signal accordingly to the input data.
Standard clock input pin for PWM circuit. One clock cycle is equivalent to the minimum
pulse width of the PWM output.
Selection signal input pin for all output adjustment functions. All output adjustment is fixed
to 100% when this signal is Low. All bit adjustments become effective when it is High.
It is not influent anything to all output adjustment by PWM clock.
Selection signal input pin for dot adjustment function. Dot adjustment value is fixed to
100% when this signal is Low. Dot adjustment becomes effective when it is High.
Reset signal input pin. Setting and registered data are reset when it is Low.
A reset also releases TSD.
Connection confirmation signal input pin for an LED. When this signal is High, all outputs
are ON.
This signal should normally be kept Low.
Connection pin of resistor for setting for the current.
Open-collector monitor pin for TSD circuit. When the TSD circuit detects an abnormal
temperature, this signal is turned ON. IO monitor the TSD circuit connect this pin to a
pull-up resistor. ALARM1 is independent of the RESET signal.
Open-collector monitor pin for output-open detection circuit. When an open output is
detected, this signal is turned ON.
Pins for the device testing. Connect all these pins to ground.
