PT4402 - 3/4 Channel Parallel White/Blue LED Drivers

Download the PT4402 datasheet PDF. This datasheet also covers the PT4401 variant, as both devices belong to the same 3/4 channel parallel white/blue led drivers family and are provided as variant models within a single manufacturer datasheet.

General Description

The PT4401/2 is a series of White/Blue LED drivers, with PT4401 capable of driving three LEDs and PT4402 driving four LEDs.

There is no external component needed, which helps to simplify the system design and lower the system cost significantly.

Key Features

  • S z No external component required z Fixed 20mA or 15mA sinking current z Individual current sink circuit for each output to prevent short/open circuit on LEDs z PTC LED current for luminosity compensation z 3 channels (PT4401/SOT23-6) and 4 channels (PT4402/MSOP-8) available z PWM tuned LED brightness through EN pin z Supply voltage range 2.7V~6.0V z 0.1uA standby current.

PT4401/2 3/4 Channel Parallel White/Blue LED Drivers „ GENERAL DESCRIPTION The PT4401/2 is a series of White/Blue LED drivers, with PT4401 capable of driving three LEDs and PT4402 driving four LEDs. There is no external component needed, which helps to simplify the system design and lower the system cost significantly. The circuit is optimized to provide over 90% efficiency. The PT4401/2 is ideal to drive white LEDs used for Li-ion battery powered LCD displays. The LED brightness can be adjusted in real time through a PWM signal at the EN pin. The target end applications are small color LCD displays in mobile phones, smart phone, digital cameras, PDA etc. PT4401 is available in SOT-23-6 package and PT4402 in MSOP-8 package, respectively.
