上桥臂驱动器/开关

具有集成特性的高端开关是一种能够将大电流安全地转变为接地负载的电源开关,可用于艰苦的汽车环境。

意法半导体提供大量基于VIPower(垂直智能电源)技术并得到全面保护的智能高端开关。这项专有技术允许在同一芯片上集成全部数字和模拟控制与保护电路,以驱动垂直结构功率MOSFET。

高端开关与3 V和5 V CMOS输出兼容,为微控制器提供了诊断输出状态检测功能。他们可轻松地驱动电感负载和电阻负载。为了全面保护应用,这些器件内置了以下功能:

  • 过热保护
  • 开/关状态下的开路检测
  • 短路保护
  • 过压和欠压关断
  • 接地失效和Vcc失效保护功能
  • 低待机功耗
  • Vbat和Tchip监控
  • 可编程闭锁

这些器件的工作温度范围是-40 °C 至 +150 °C。ST 的高端开关产品组合包括单驱动、双驱动和四驱动产品,具有数字或模拟状态,RDS(ON)值从 4 mΩ 到 500 mΩ 不等。该产品系列提供不同的封装选项。它们可用于车身电子产品(例如接线盒、车内照明和电机控制)的电源系统。

Next-generation VIPower M0-7 intelligent high-side switches

ST's new family of VIPower M0-7 intelligent power switches provide enhanced intelligent features, improve protection and reliability, and are up to 40% smaller than competing alternatives. Pioneered by ST, intelligent high-side switches provide a more reliable and efficient replacement for conventional relays.

The VIPower family has offered advantages such as a common package style for many devices in the range. This allows tier-one suppliers to build several module variants using the same basic hardware and software so car makers can address differing requirements in international markets and offer various model specifications and options cost-effectively. The common-package approach has become widely adopted among high-side switch vendors.

In the VIPower M0-7 series, 75% of family members are available in a 5 x 4 mm package, which is 40% smaller than the smallest competing devices. This allows car electronics designers to save pc-board space and aim for smaller module sizes. Moreover, various internal design changes increase precision, enhance diagnostic feedback, and improve reliability.

Specifically, performance improvements include greater protection against short circuits, more accurate voltage and temperature feedback, increased current-sense precision, and best-in-class electromagnetic emission (EMI) performance.
