VNH7100AS 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 GAPGCFT00648 driver and two low-side switches. Both switches are designed using Features STMicroelectronics well known and proven proprietary VIPower M0 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 100 mtyp VNH7100AS 12A 41V assembled in SO-16N package on electrically per leg) isolated leadframes. 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 MultiSense to the microcontroller. The Thermal shutdown MultiSense pin allows to monitor the motor current by delivering a current proportional to the Cross-conduction protection motor current value. Current and power limitation The PWM, up to 20 kHz, allows to control the Very low standby power consumption speed of the motor in all possible conditions. In all Protection against loss of ground and loss of cases, a low level state on the PWM pin turns off V CC both the LS and LS switches. A B PWM operation up to 20 kHz Table 1.
