2-channel Constant Current Regulator

2-channel Constant Current Regulator

INTRODUCTION

The HM7502 is a 2-channel LED driver, designed for current

regulation. It may be used in various current regulation circuits,

especially suitable for LED applications. It lets LEDs work

under stable current and avoid brightness unstable caused by

current change, while its low voltage can reduce power

consumption.

The connection of the VDD power pin may also be used for

brightness control of LEDs via PWM signals; therefore suitable

for applications that need brightness adjustment.

The connection of REXT pin can be used for the control of

output current, to control and drive more LEDs. When REXT is

open, VCH1, VCH2 pins may provide 30mA of current. To

achieve operations with VCH1/VCH2 current over 60mA,

connect the ICs in parallel.
