MP3320A
DESCRIPTION
The MP3320A is a 4-channel, self-adaptive, charge pump RGB LED driver that operates across a wide 1.8V to 5.5V input voltage (VIN) range. Each channel can reach a maximum current of up to 51m A and a maximum output voltage (VOUT) of up to 5.5V.
The MP3320A integrates an I2C interface with up to 16 configurable I2C addresses via an external resister. Each channel can be enabled or disabled through the I2C.
The MP3320A employs both separated pulsewidth modulation (PWM) dimming and analog dimming for each LED channel, as well as 10-bit PWM dimming and 8-bit analog dimming for each channel. Phase shift is also integrated during PWM dimming to reduce inrush current and eliminate audible noise.
To ensure system reliability, the MP3320A integrates rich protections including LED open protection, LED short protection, over-voltage protection (OVP), and over-temperature protection.
The MP3320A is available in a QFN-14 (2mmx2mm) package.
