VNH3ASP30-E

The VNH3ASP30-E is a full bridge motor driver intended for a wide range of automotive applications. The device incorporates a dual monolithic High-Side drivers and two Low-Side switches. The High-Side driver switch is designed using STMicroelectronic's well known and proven proprietary VIPower™ M0 technology that allows to efficiently integrate on the same die a true Power MOSFET with an intelligent signal/protection circuitry.

The VNH3ASP30-E Low-Side switches are vertical MOSFETs manufactured using STMicroelectronic's proprietary EHD ('STripFET™') process. The three dice are assembled in MultiPowerSO-30 package on electrically isolated leadframes. This package of VNH3ASP30-E, specifically designed for the harsh automotive environment offers improved thermal performance thanks to exposed die pads. Moreover, its fully symmetrical mechanical design allows superior manufacturability at board level.The input signals INA and INB can directly interface to the microcontroller to select the motor direction and the brake condition. The DIAGA/ENA or DIAGB/ENB, when connected to an external pull-up resistor, enable one leg of the bridge. They also provide a feedback digital diagnostic signal. The normal condition operation is explained in the truth table on page 7. The CS pin allows to monitor the motor current by delivering a current proportional to its value. The PWM, up to 20KHz,lets us to control the speed of the motor in all possible conditions. In all cases, a low level state on the PWM pin will turn off both the LSA and LSB switches. When PWM rises to a high level, LSA or LSB turn on again depending on the input pin state.
