STP4CMPQTR Product Details

The STP4CMPQTR is a charge-pump-based 4-channel LED driver designed for RGB illumination or LCD display backlighting. The STP4CMPQTR works off a battery with an input voltage between 2.7 V and 5.5 V. The device generates regulated current sinks with high absolute and channel-to-channel accuracy to drive up to 4 LEDs. It can support LEDs with forward voltage as high as 3.8 V. The current sink for each channel can be set with 4 individual external resistors. Each channel is controlled independently. The PWM control can be applied directly to the 4 EN (enable) pins to provide brightness control. When enabled, the charge pump, which uses a small ceramic bucket capacitor between C1P and C1N, operates to regulate the VOUT with a clamping voltage at typ. 5 V. The tiny QFN20 (1.8x3.2 mm) package allows the device to be also used for applications with space limitations.

Feature

  • Operating voltage range: VCC 2.7 V to 5.5 V
  • Full RGB function support
  • 4-channel LED driver with individual ON/OFF control directly from input pins
  • Individually programmable output current for the 4 channels through 4 external resistors with a max. capability of 30 mA
  • Absolute output current accuracy of max. ±7% and channel-to-channel mismatch of max. ±4%
  • Selectable charge pump enable/disable
  • Thermal protection
  • Small QFN20 (1.8x3.2 mm) package
