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 I2C addresses. 2 Applications This allows connecting up to four parallel devices in • Fun Lights one I2C bus. The device requires only one small, low- cost ceramic capacitor. • Indicator Lights • Keypad RGB Backlighting and Phone Cosmetics Device Information(1) PART NUMBER PACKAGE BODY SIZE (MAX) LP5562 DSBGA (12) 1.648 mm × 1.248 mm (1) For all available packages, see the orderable addendum at the end of the data sheet.
