EV-VNH7070AS STMicroelectronics

EV-VNH7070AS VNH7070AS Evaluation Board Data brief recommendation) is enabling the user to directly connect the load, the power supply and the microcontroller without any additional effort in external component design and connection. VNH7070AS 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 an intelligent signal/protection circuitry. The three dies are assembled in SO-16N package on electrically isolated leadframes. Moreover, its fully symmetrical mechanical design Features allows superior manufacturability at board level. The input signals INA and INB can directly Max transient supply voltage V 41 V CC interface the microcontroller to select the motor direction and the brake condition. A SEL0 pin is Operating voltage range V 4 to 28 V CC available to address the information available on Typ. on-state resistance (per R 70 m the MultiSense to the microcontroller. The ON Ch) MultiSense pin allows to monitor the motor current by delivering a current proportional to the Current limitation (typ) I 15 A LIMH motor current value. Stand-by current (max) I 1 A STBY The PWM, up to 20 kHz, allows to control the speed of the motor in all possible conditions.. Table 1.
