Pin Description
PIN No.
SSOP28/HSOP28: 1
QFN32: 5
PIN NAME
VCC Supply voltage terminal.
FUNCTION
SSOP28/HSOP28: 2
QFN32: 6
SSOP28/HSOP28: 3
QFN32: 9
Output enable terminal:
EN ‘H’ for all outputs are turned off ,
‘L’ for all outputs are active.
LAT
Input terminal of data strobe. Data on shift register goes through at the rising
edge of LAT (edge trigger). Otherwise, data is latched.
SSOP28/HSOP28: 4
QFN32: 10
CLK
Synchronous clock input terminal for serial data transfer. Data is sampled at the
rising edge of CLK.
SSOP28/HSOP28: 5
QFN32: 11
DAI Serial data input terminal.
SSOP28/HSOP28: 6
QFN32: 12
SSOP28/HSOP28:
7~22
QFN32: 13~28
Input open/short detection selection:
‘H’ for LED short detection mode,
OS
‘L’ for LED open detection mode,
‘Edge’*1 for smart detection mode.
OUT0~15 Sink constant-current outputs (open-drain).
SSOP28/HSOP28: 23
QFN32: 29
DAO
Serial data output terminal.
SSOP28/HSOP28: 24
QFN32: 30
SSOP28/HSOP28: 25
QFN32: 31
ALARM
SDO
Output open drain terminal: (connected to a pull-high resistor)
‘H’ for normal conditions,
‘L’ for LED open/short or chip overheated.
Serial data output trigger mode selection:
‘H’ means data is shifted out on synchronization to falling edge of CKO,
‘L’ means data is shifted out on synchronization to rising edge of CKO.
SSOP28/HSOP28: 26
QFN32: 32
REXT
External resistors connected between REXT and GND for output current value
setting.
SSOP28/HSOP28: 27
RESERVED Terminal for testing, user should leave this pin open.
QFN32: 3
SSOP28/HSOP28: 28
Thermal pad
QFN32: 1, 2, 4, 7, 8
Thermal pad
GND
Ground terminal.
*1 Rising edge or falling edge. See detailed description (page 14~16).
