SNVS488A –JUNE 2007–REVISED MARCH 2013

Programmable LED Driver

Check for Samples: LP5522

FEATURES

DESCRIPTION

The LP5522 is a simple single wire programmable

LED controller in six bump DSBGA package. It

provides constant current flow through high side

driver. Output current can be set from 1 mA to 20 mA

by using an external resistor on the ISET pin. If no

external resistor is used, output current is set to 5 mA

default current. The LP5522 is controlled using only

one signal. The signal controls either directly the LED

driver or it launches previously programmed blinking

sequence.

•

Programmable Blinking Sequence

–

1 to 3 Programmable Pulses

1 ms to 255 ms LED on Time

10 ms to 2500 ms LED Off Time

Single or Continuous Run of Programmed

Blinking Sequence

•

Constant Current High Side Output Driver

Adjustable Current with External Resistor

0.2 µA Typical Shutdown Current

The LP5522 works autonomously without a clock

signal from the master device. Very low LED driver

headroom voltage makes possible to use supply

voltages close to LED forward voltage. Current

consumption of the LP5522 is minimized when LED

is turned off and once controller is disabled all

supporting functions are also shut down. Very small

DSBGA package together with minimum number of

external components is a best fit for handheld

devices.

Autonomous Operation without External Clock

DSBGA-6 Package with 0.4 mm Pitch:
