NXP Semiconductors MC33816栅极驱动器
Freescale MC33816栅极驱动器是一款用于汽车引擎控制应用的12路栅极驱动器IC。该IC包含5个外部MOSFET高边预驱动器和7个外部MOSFET低边预驱动器。MC33816为MOSFET’提供了一个灵活的解决方案，实现了多样化控制和最佳延迟时间。栅极驱动、诊断和保护通过4个独立的微内核、2个代码RAM和2个数据RAM分区来管理。该IC包含两个具有过压和欠压监视和保护的内部稳压器，有4个电流检测模块和VDS监视以通过串行外设接口（SPI）进行故障检测和显示。器件包括每高边预驱动器一个独立电荷泵输出以及一个高压DC-DC转换器低边预驱动器。这些特性外加经济高效的封装形式，使得 MC33816成为动力系统引擎控制应用的理想之选。
The MC33816 contains two internal voltage regulators with overvoltage and undervoltage monitoring and protection. There are four current sense modules and VDS monitoring for fault detection and annunciation via a serial peripheral interface (SPI). The device includes both individual charge pump outputs for each high-side pre-drivers and a high-voltage DC-DC converter low-side pre-driver.
These features along with cost effective packaging, make the MC33816 ideal for powertrain engine control applications
