EVQ3326-R-00A 16 Channels, 50mA/Ch, LED Driver with Separated PWM Analog Dimming and 2 I C Interface Evaluation Board, AEC-Q100 DESCRIPTION FEATURES The EVQ3326-R-00A is an evaluation board Wide 4V to 16V Input Voltage Range designed for the MPQ3326, a 16-channel 16 Channels, 50mA/Ch Maximum (V IN WLED driver that can operate from a wide 4V to 4.5V) 16V input voltage range. The MP3326 applies LED Current Configured by External 16 internal current sources in each LED string Resistor terminal. The LED current of each channel is 6-Bit Analog Dimming for Each Channel set by an external current-setting resistor. The 12-Bit PWM Dimming for Each Channel maximum current for each channel is 50mA (V IN Selectable 220Hz, 250Hz, 280Hz, or 330Hz 4.5V). PWM Dimming Frequency 2 Refresh Signal Output The device integrates an I C interface with up to 2 2 10 configurable I C addresses via an external I C Interface resistor. This means the MPQ3326 can support 10 Addresses Configurable via External up to 10 cascaded ICs to drive the LED array. Resistor Each channel can be enabled or disabled Configurable LED Current Slew Rate 2 through the I C. 40s Phase Shift Fault Indicator The MPQ3326 employs both separated PWM LED Open Protection dimming and analog dimming for each LED LED Short Protection with Configurable channel, as well as 12-bit resolution PWM Threshold dimming and 6-bit analog dimming for each Under-Voltage Lockout (UVLO) channel. To optimize EMI/EMC performance, the LED current ramp rate and phase shift can Over-Temperature Protection (OTP) be configured. ELV Directive II Compliant Available in a QFN-24 (4mmx4mm) The device can output a refresh signal from the Package RFSH/FLT pin, and the refresh signal frequency AEC-Q100 Grade 1 can be set by the register. APPLICATIONS LED open and short protection, and over- temperature protection (OTP) are integrated Automotive Lights into the device. The fault indicator pulls low if a Automotive Displays protection is triggered, and then the Instruments Clusters corresponding fault register is set. General Industrial Displays The MPQ3326 is AEC-Q100 qualified. It is All MPS parts are lead-free, halogen-free, and adhere to the RoHS directive.
