SP7121 Détails du produit

GENERAL DESCRIPTION
The SP7121 LED driver provides a simple solution for a matched current source for any color common cathode LEDs. The common cathode connection allows the user to increase the LED power dissipation by having the cathodes heat sinked to the ground plane of the circuit board. The SP7121 output current value is set by an external resistor. At shutdown mode (EN pin is LOW), the supply current drops to .04µA typical. The SP7121 driver is available in a small footprint 6-pin SOT23-6 package.

FEATURES
• LED Driver for common cathode parallel connected LEDs
• Ultra Low Dropout Voltage of 300mV @ 25mA
• No EMI, no switching noise
• Integrated current matching
• PWM brightness control
• Enable/Shutdown control
• Shutdown current < 1µA
• Adjustable Output current up to 30mA per channel
• Available in RoHS Compliant, Lead Free Package: Small footprint SOT23-6

TYPICAL APPLICATION
• Mobile Phones
• PDA, DSC, MP3 players
• Handheld Computers
• Keypads and display backlight
