DESCRIPTION
NO.
NAME
Output voltage sense connection for overvoltage sensing. Connect OVP to the positive terminal of the
A1
OVP
IN
output capacitor.
Input terminal to high voltage current sink 3 (40 V maximum). The boost converter regulates the
A2
ILED3
IN
minimum of ILED1, ILED2, or ILED3 to 0.4V.
Input terminal to high voltage current sink 2 (40 V maximum). The boost converter regulates the
A3
ILED2
IN
minimum of ILED1, ILED2, or ILED3 to 0.4V.
Input terminal to high voltage current sink 1 (40 V maximum). The boost converter regulates the
A4
ILED1
IN
minimum of ILED1, ILED2, or ILED3 to 0.4V.
B1
ALS1
IN
Ambient light sensor input 1.
B2
ALS2
IN
Ambient light sensor input 2.
B3
HWEN
IN
Active high hardware enable. Pull this pin high to enable the LM3532. HWEN is a high impedance input.
B4
IN
IN
Input voltage connection. Bypass IN to GND with a minimum 2.2-µF ceramic capacitor.
C1
PWM2
IN
External PWM brightness control Input 2.
C2
PWM1
IN
External PWM brightness Ccontrol Input 1.
C3
INT
OUT
Programmable Interrupt pin. INT is an open-drain output that pulls low when the ALS changes zones.
