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 SO- 16N package on electrically isolated leadframes. Moreover, its fully symmetrical mechanical design allows superior manufacturability at board level. Features The input signals INA and INB can directly interface the microcontroller to select the motor Max transient supply voltage V 41 V CC direction and the brake condition. A SEL0 pin is available to address the information available on Operating voltage range V 4 to 28 V CC the MultiSense to the microcontroller. The Typ. on-state resistance (per Ch) R 70 m MultiSense pin allows to monitor the motor ON current by delivering a current proportional to the Current limitation (typ) I 15 A motor current value. LIMH The PWM, up to 20 kHz, allows to control the Stand-by current (max) I 1 A STBY speed of the motor in all possible conditions. Table 1.
