MP3324 - 8-Channel 100mA/Ch LED Driver

General Description

The MP3324 is an 8-channel white LED (WLED) driver that operates from a wide 4V to 16V input voltage (VIN) range.

The MP3324 applies eight internal current sources in each LED string terminal.

The LED current (ILED) of each channel is set by an external current-setting resistor.

Key Features

  • include LED open-load protection (OLP), LED short-load protection (SLP), and over-temperature protection (OTP). The device also features fault indication. If a protection function is triggered, then the RFSH/FLT pin is pulled low, and the corresponding fault register is set. The MP3324 is available in a QFN-24 (4mmx4mm) package.

MP3324 8-Channel, 100mA/Ch, LED Driver with Separated PWM/Analog Dimming and I2C Interface DESCRIPTION The MP3324 is an 8-channel white LED (WLED) driver that operates from a wide 4V to 16V input voltage (VIN) range. The MP3324 applies eight internal current sources in each LED string terminal. The LED current (ILED) of each channel is set by an external current-setting resistor. Each channel has a 100mA maximum current (while VIN ≥ 4.5V). The device integrates an I2C interface. There are ten different I2C addresses that can be configured via an external resistor. This means the MP3324 can support up to ten ICs that have been cascaded to drive an LED array. Each channel can be enabled or disabled via the I2C.
