製品概要
概要
The VNH9090AQ 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. All switches are designed using STMicroelectronics well known and proven proprietary VIPower technology that allows to efficiently integrate on the same die a true Power MOSFET with an intelligent signal/protection circuitry. The three dices are assembled in a QFN 6x6 triple pad 26+2L package equipped with three exposed islands for optimized dissipation performances. This package is specifically designed for the harsh automotive environment and offers improved thermal performance thanks to exposed die pads. The input signals INA and INB can directly interface the microcontroller to select the motor direction and the brake to VCC condition. Two selection pins (SEL0 and SEL1) to address the information are available on the multisense to the microcontroller. The multisense pin allows monitoring the motor current by delivering a current proportional to the motor current value and provides the diagnostic feedback and Case temperature according to the implemented truth table. The PH_OUT pin provides feedback on the OUTA and OUTB state for safety-relevant functions. The PWM, up to 25 kHz, allows controlling the speed of the motor in all possible conditions or selecting the brake to GND condition. In all cases, a low-level state on the PWM pin turns off both the LSA and LSB switches.
