Description
The VHN5019A-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 STMicroelectronics’ 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 circuit.
The three dice are assembled in a MultiPowerSO-30 package on electrically isolated lead-frames.
This package, specifically designed for harsh automotive environments 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 condition.
The DIAGA/ENA or DIAGB/ENB, when connected to an external pull-up resistor, enables one leg of the bridge.
It also provides a feedback digital diagnostic signal.
The CS pin allows to monitor the motor current by delivering a current proportional to its value when CS_DIS pin is driven low or left open.
The PWM, up to 20 KHz, lets us control the speed of the motor in all possible conditions.
In all cases, a low-level state on the PWM pin turns off both the LSA and LSB switc...
