描述 Description

The VNH3SP30-E is a full-bridge motor driver intended for a wide range of automotive applications. The device incorporates a dual monolithic high-side driver (HSD) and two low-side switches. The HSD switch is designed using STMicroelectronics proprietary VIPower™ M0-3 technology that efficiently integrates a true Power MOSFET with an intelligent signal/protection circuit on the same die.

The low-side switches are vertical MOSFETs manufactured using STMicroelectronics proprietary EHD (“STripFET™”) process. The three circuits are assembled in a MultiPowerSO-30 package on electrically isolated lead frames. This package, specifically designed for the harsh automotive environment, offers improved thermal performance thanks to exposed die pads. Moreover, its fully symmetrical mechanical design provides superior manufacturability at board level. The input signals INA and INB can directly interface with the microcontroller to select the motor direction and the brake condition. Pins 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 operating conditions are explained in the truth table. The speed of the motor can be controlled in all possible conditions by the PWM up to kHz. 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 will turn on again depending on the state of the input pin.
