Constant current SINK terminal to drive LED (Channel 5)
Constant current SINK terminal to drive LED (Channel 6)
Constant current SINK terminal to drive LED (Channel 7)
Constant current SINK terminal to drive LED (Channel 8)
Current sense input to monitor MOSFET current.
Power ground
Switching n-MOSFET Gate-Driver Output.
MOSFET Gate-driver Supply input. Connect a resistor between VREG and
DRV to power the MOSFET driver with the internal 5V regulator. Bypass DRV
to GND with a minimum of 0.1μF ceramic capacitor.
TEST terminal. Connect to VREG.
5V Regulator Output for internal circuits.
Connect to GND with minimum of 1.0μF capacitor as close to the device.
Power Supply input. Connect a 7 to 36V supply to VCC. Bypass VCC to GND
with a ceramic capacitor.
Input chip enable signal, EN=high : operation-mode or standby-mode
EN=Low : shut down mode
Monitor for Over voltage detection and Under voltage detection.
Under voltage lockout input terminal for external Power Supply.
Lockout voltage is 1.15V(TYP) at VUVLO rising
Error signal output by fault protection control.
Terminal which Setting latch up time for fault detection (OVD,LVD,OCD).
Connect Capacitor between CFIL and GND depend on setting time.
Terminal for controlling compensation point of AMP which controls output
voltage. Connect RC between COMP and GND.
Serial I/F Setting input
All PWM individual control mode: Connect to VREG.
Over voltage detection threshold : 3.5V (TYP)
Under voltage detection threshold : 0.2V (TYP)
