A701/2
6 CHANNELS ADJUSTABLE
CONSTANT CURRENT LED DRIVER
DESCRIPTION
FEATURES
A701/2 are adjustable constant current drivers for
LED applications. Six regulated current ports are
designed to provide uniform and pure DC constant
current sinks for driving LEDs within a large range VF
variation.
A701/2 provide users 6-channel constant current
ports to match LEDs with equal current. Users may
program the output current from 5mA to 40mA through
an external resistor, R_SET, which gives user flexibility in
controlling the light intensity of LEDs.
Two kinds of control logic, active high and active
low, for Output Enable pin (OE/OE pin) are provided for
user’s varies applications. It could precisely adjust LED
brightness from 0% to 100% via OE/OE pin with Pulse
Width Modulation signal.
The thermal protection function protects IC from
over temperature (150°C) damage. Also, the thermal pad
enhances the package power dissipation.
6 constant-current output channels
Output current deviations: ±3% between channels,
±7% between ICs.
Output current programmable through external
resistor.
Constant output current range: 5mA~40mA
Wide supply voltage range: 6V~50V (A702)
75V output sustaining voltage
1uA Shut-down current
2 kinds of control logic for Output Enable pin
