VNH7070AS Automotive fully integrated H-bridge motor driver Datasheet - production data Description The device is a full bridge motor driver intended SO-16N for a wide range of automotive applications. The device incorporates a dual monolithic high-side driver and two low-side switches. GAPGCFT00648 Both switches are designed using Features STMicroelectronics well known and proven proprietary VIPower M0-7 technology that allows to efficiently integrate on the same die a true Type R I V DS(on) out CCmax Power MOSFET with an intelligent signal/protection circuitry. The three dies are 70 mtyp VNH7070AS 15A 41V assembled in SO-16N package on electrically per leg) isolated lead-frames. Moreover, its fully symmetrical mechanical design Automotive qualified allows superior manufacturability at board level. Output current: 15 A The input signals IN and IN can directly A B 3 V CMOS-compatible inputs interface the microcontroller to select the motor direction and the brake condition. A SEL0 pin is Undervoltage shutdown available to address the information available on Overvoltage clamp the CS to the microcontroller. The CS pin allows Thermal shutdown to monitor the motor current by delivering a current proportional to the motor current value. Cross-conduction protection The PWM, up to 20 kHz, allows to control the Current and power limitation speed of the motor in all possible conditions. In all Very low standby power consumption cases, a low level state on the PWM pin turns off both the LS and LS switches. A B Protection against loss of ground and loss of V CC Table 1.
