说明

采用SOI技术设计的全保护三半桥驱动器，特别允许在汽车和工业应用中通过微控制器控制电机。三个高侧和三个低侧驱动器中的每一个，内部连接以形成三个半桥，可以驱动高达1.0A的电流。其高PWM频率能力可以平滑地控制两个直流电机或一个无刷直流电机。

特性

• Supply voltage up to 40V
• RDSon typically 0.8Ω at 25°C, maximum 1.5Ω at 150°C
• Up to 1.0A output current
• Three half-bridge outputs formed by three high-side and three low-side drivers
• Capable of switching loads such as DC motors, bulbs, resistors, capacitors, and inductors
• PWM capability up to 25kHz for each high-side output controlled by external PWM signal
• No shoot-through current
• Very low quiescent current IVS < 2μA in standby mode over total temperature range
• Outputs short-circuit protected
• Selective overtemperature protection for each switch and over temperature prewarning
• Undervoltage protection
• Various diagnostic functions such as shorted output, open load, overtemperature and power- supply fail detection
• Serial data interface, daisy chain capable, up to 2MHz clock frequency
• QFN18 package
