Kit Description
Overview
The ZLED7002KIT-E1 Evaluation Kit provides a quick and easy method for evaluating the ZLED7002 IC
product within its basic application circuit. Reading the
ZLED7002 Data Sheet
before using the Demo Kit is
recommended for understanding of the operation of the ZLED7002 IC product and the application circuit on
this evaluation board.
The ZLED7002 toggle (side-step) dual-channel LED driver is one of ZMDI’s LED driver family ICs. It operates
in the lower DC voltage supply range of 2.7V to 5.5V. This unique LED driver is capable to control a MAIN
channel and a SUB channel, respectively. Typically, only one of the two channels is active and the ZLED7002
toggles between the channels automatically controlled by the supply voltage level thus the related voltage at
the UV (under-voltage protection) pin.The ZLED7002 IC can drive LEDs with a current up to 250mA.
The main features of ZLED7002 driver are:
The Automatic MAIN channel short-circuit protection switches the output current to the SUB channel if
the MAIN LED is shorted
Under-voltage power supply detection
Over-temperature protection
Voltage supply: 2.7V to 5.5V DC
Figure 1 shows the top view of the populated kit PCB.

Power Supply
The Evaluation Board contains a standard battery holder for 3xAA batteries for power supply. Optional a two
pin connector (J3) is present for an external power supply.
Note:
Since the system is not reverse polarity protected, exercise caution when connecting an external
power supply or inserting/replacing batteries.
Never use batteries in parallel to an external power supply.
Remove batteries in case the kit is not going to be used for a long time.

Interface
The Evaluation Board has two LEDs – MAIN LED and a SUB LED (one LED per IC channel).
Jumper setup for configuring of the ZLED7002 working modes:
J1
– Under Voltage protection level selection. This jumper determines how this level will be defined –
by the potentiometer RP1 or by the voltage divider R3 and R4. The resistors R3 and R4 are not
populated. The user must choose appropriate values..
J6
– SUB LED working mode. Two options are available – SUB LED to be driven from ZLED7002 or
to be directly connected to the supply voltage.
J7
– MAIN LED working mode. Two options are available – MAIN LED to be driven from ZLED7002
or to be directly connected to the supply voltage.
J8
– SUB CHANNEL working mode. Two options are available – SUB CHANNEL drives SUB LED or
MAIN LED.
Please refer also to the table printed on the board!
J5
– Current selection jumper. User can chose between five predefined current rates. In addition to
that a custom current rate is electable. The desired custom current rate can be set by populating of
R10 with an appropriate resistor value (see the Datasheet for details).
J2
- Applying a user selectable resistor to the SUB LED
J3
– Allows connecting of an external power supply
J4
– Allows connecting of an ampere meter
SW1
– main power switch
