Introduction

AI Translation

The MAX20090 is a single-channel high-brightness LED (HB LED) driver for automotive front-light applications such as high beam, low beam, daytime running lights (DRLs), turn indicators, fog lights, and other LED lights. It can take an input voltage from 5V to 65V and drive a string of LEDs with a maximum output voltage of 65V. The device senses output current at the high side of the LED string. High-side current sensing is required to protect for shorts from the output to the ground or battery input. It is also the most flexible scheme for driving LEDs, allowing boost, high-side buck, SEPIC mode, or buckboost-mode configurations. The PWM input provides LED dimming ratios of up to 1000:1, and the ICTRL input provides additional analog dimming capability in the controller. The device also includes a fault flag (̅F̅L̅T̅) that indicates open string, shorted string, and thermal shutdown. The device has built-in spread-spectrum modulation for improved electromagnetic-compatibility performance. The device can also be used in zeta and Cuk converter configurations, if necessary in some applications. The MAX20090 is available in a space-saving (4mm×4mm), 20-pin TQFN, 20-pin side-wettable TQFN, or a 20-pin TSSOP package and is specified to operate over the -40°C to +125°C automotive temperature range.
