9通道红外LED驱动器,KTD2041,KTD2042,Kinetic Technologies

作为电源管理和视频/音频接口解决方案的领导者，芯凯电子今日宣布发布其首款红外LED驱动，以满足日益增长的高清夜间可视门铃和安防监控摄像机市场的需求。KTD2041是首款采用自适应降压转换器来恒流源电压余量的红外LED驱动芯片，以最大限度地减少功率消耗，延长电池使用寿命。

KTD2041具有九个可独立控制的高精度、低压差的恒流源，使用1MHz I²C控制接口提供6位线性调光控制，步长0.5mA，最大电流为32mA/LED。3mmx3mm的UQFN-20精巧封装设计。KTD2041可根据LED恒流源所需的电压余量自动调节输出电压，以最大限度地降低功耗。1MHz（默认值）高效降压调节器实现自动调节接通时间，可最大限度地减少器件数量，并允许使用小尺寸电感和电容。

“芯凯电子不懈致力于满足客户需求，为客户打造定制化个性产品“，芯凯电子资深市场总监Erik Ogren表示。“KTD2041非常适用于使用先进视频处理技术的可视门铃和安防摄像机等电池供电的摄像设备。KTD2041的每个红外LED通道都可以自动开启或关闭，以便将红外光聚焦在特定方向，从而优化效率。”

KTD2041集成逐周期电流限制、输入欠压锁定（UVLO）、输出过压保护、LED故障（开路或短路）保护和热关机保护等诸多保护功能。

KTD2041为驱动红外LED而设计，其100mV的低压差恒流源，也使其同样适用于驱动更高VF的RGB LED。KTD2042可实现引脚到到引脚的功能性兼容，但经过修改，可以驱动三个32毫安/通道的RGB LED或更高电流的应用。可通过多个LED通道并联来实现为每个LED提供更高电流输出。

产品主要特点:

●2.7V至5.5V输入电压工作范围

●九个高精度恒流源

●±1%典型电流匹配

32mA在32mA电流时±2%典型电流精度

每通道32mA LED驱动电流

●带I²C的6位电流调光控制

●独立的开/关控制

●支持独立和统一调光

●高效降压调节器

●集成200/100mΩ高边/低边晶体管

●自适应开启时间控制，默认1MHz开关频率，具有制造厂家可编程的1.5MHz、2MHz和2.5MHz选项

●自适应VOUT控制

●轻负载条件下，可选择自动跳过模式或强制PWM模式

●140μA典型空载工作电流

●漏极开路故障信号输出和故障复位

●UQFN-20(3mmx3mm)小尺寸封装
