Infineon IFX007T大电流PN半桥马达驱动解决方案
Infineon公司的IFX007T是集成的大电流半桥马达驱动器,是工业和多用途NovalithIC™系列的一部分,在同一封装内包括一个P沟高边MOSFET和一个N沟低边MOSFET以及集成的驱动器.由于P沟高边开关不需要充电泵,因此最小化EMI;由于集成的驱动器IC,具有逻辑电平输入,电流检测诊断,转换速率调整,死区时间产生和对超温,欠压和过流与短路的保护,因此和MCU的接口变得很容易,为保护大电流PWM马达驱动提供非常小板空间的成本最优化解决方案.@25℃时的最大通路电阻12.8 mΩ,高边最大为6.5 mΩ,低边最大为6.3 mΩ,限流水平为55A,具有闩锁特性和欠压关断特性,工作电压高达40V,JESD47I资格,IFX007T和其它IFX007T组成H桥或其它3相驱动配置,主要用在马达驱动.本文介绍了IFX007T主要特性,框图和应用电路,以及IFX007T马达控制板主要特性,Arduino马达控制电路图和PCB布局图.
The IFX007T is an integrated high current half bridge for motor drive applications. It is part of the Industrial &Multi PurposeNovalithIC™ family containing one p-channel high-side MOSFET and one n-channel low-sideMOSFET with an integrated driver IC in one package. Due to the p-channel high-side switch the need for acharge pump is eliminated thus minimizing EMI. Interfacing to a microcontroller is made easy by the integrated driver IC which features logic level inputs, diagnosis with current sense, slew rate adjustment, deadtime generation and protection against overtemperature, undervoltage, overcurrent and short circuit.
