SNVS820A –APRIL 2013–REVISED SEPTEMBER 2015
LP5562 Four-Channel LED Driver With Programmable Lighting Sequences
1 Features 3 Description
The LP5562 is a four-channel LED driver designed to
1
• Four Independently Programmable LED Outputs
produce variety of lighting effects. The device has a
With 8-Bit Current Setting (From 0 mA to 25.5 mA
program memory for creating variety of lighting
With 100-μA Steps) and 8-Bit PWM Control
sequences. When the program memory has been
• Typical LED Output Saturation Voltage 60 mV and
loaded, the LP5562 can operate independently
Current Matching 1%
without processor control.
• Flexible PWM Control for LED Outputs
The LP5562 is able to automatically enter power save
• Automatic Power-Save Mode With External Clock
mode, when LED outputs are not active and thus
lowering current consumption.
• Three Program Execution Engines With Flexible
Instruction Set
Four independent LED channels have accurate
programmable current sinks, from 0 mA to 25.5 mA
• Autonomous Operation With Program Execution
with 100-μA steps and flexible PWM control. Each
Engines
channel can be configured into each of the three
• SRAM Program Memory for Lighting Pattern
program execution engines. Program execution
Programs
engines have program memory for creating desired
• DSBGA 12-Pin Package, 0.4-mm Pitch
lighting sequences with PWM control.
The LP5562 has four pin-selectable I
2
C addresses.
2 Applications
This allows connecting up to four parallel devices in
• Fun Lights
one I
2
C bus. The device requires only one small, low-
cost ceramic capacitor.
• Indicator Lights
• Keypad RGB Backlighting and Phone Cosmetics
