EV-VNH7070BAS

EV-VNH7070BAS VNH7070BAS Evaluation Board Data brief connect the load, the power supply and the microcontroller without any additional effort in external component design and connection. VNH7070BAS is a full bridge motor driver intended for a wide range of automotive applications. The device incorporates a dual monolithic high-side driver and two low-side switches. Both switches are designed using ST proprietary VIPower M0 technology that allows to efficiently integrate on the same die a true Power MOSFET with intelligent signal/protection circuitry. The three dies are assembled in a SO16N package on electrically isolated leadframes. Moreover, its fully symmetrical mechanical design allows superior manufacturability at board level. Features Max transient supply voltage VCC 41 V Operating voltage range VCC 4 to 28 V Typ. on-state resistance (per Ch) RON 70 mΩ Current limitation (typ) ILIMH 15 A Stand-by current (max) ISTBY 1 µA  Simple single IC application board dedicated for VNH7070BAS  Provides electrical connectivity and thermal heat-sinking for easy prototyping The input signals INA and INB can directly interface the microcontroller to select the motor direction and the brake condition. A SEL0 pin is available to address the information available on the MultiSense to the microcontroller. The MultiSense pin allows to monitor the motor current by delivering a current proportional to the motor current value. The PWM, up to 20 kHz, allows to control the speed of the motor in all possible conditions. Table 1.
