Renesas Electronics ISL99227智能功率级
Renesas/Intersil ISL99227智能功率级 (SPS) 设计用于与Intersil ISL681xx数字多相 (DMP) 控制器配套使用。ISL99227提供集成的高精度电流和温度监控器，可以反馈到控制器以完成多相直流/直流系统。这些器件通过消除 DCR 感测网络和相关热补偿来简化设计和提高性能。通过专用 LEFT 控制引脚支持轻载效率。该器件采用热增强型5.0mm x 5.0mm PQFN封装，只需极小的总体PCB空间。 ISL99227 SPS兼容3.3V，兼容5.0V，具有三态PWM输入。该智能功率级与Intersil的多相PWM控制器配搭使用，即便在异常工作条件下也能提供强大的解决方案。ISL99227 还通过集成的 UVLO、过温和过流等故障保护来提高系统性能和可靠性。开漏故障报告引脚简化了SPS和Intersil控制器之间的握手通信，可用于在启动和故障情况期间禁用控制器。
Renesas Electronics ISL99227 SPS features a 3.3V compatible, 5.0V compatible, tri-state PWM input. Working together with the multiphase PWM controllers, the Smart Power Stage provides a robust solution in the event of abnormal operating conditions. The ISL99227 also improves system performance and reliability with integrated fault protection of UVLO, over-temperature, and overcurrent. An open-drain fault reporting pin simplifies the handshake between SPS and Intersil controllers and can be used to disable the controller during start-up and fault conditions.
