The VHN5019A-E is a full bridge motor driver suitable for various automotive applications. The device contains dual monolithic high-side drivers and two low-side driver switches. High-end driver switch designed
Efficient integration of power MOSFETs and intelligent signal/protection circuits on the same die using STMicroelectronics' well-known and proven proprietary VIPower® M0 technology.



When connecting VNH5019ATR-E, DIAGA/ENA or DIAGB/ENB are connected to external pull-up resistor bridge. It also provides a digital feedback diagnostic signal. The CS pin allows monitoring of motor current. When the CS_DIS pin is

Drive low or open left. PWM up to 20KHz, in all cases the low level state turns off the LSA and LSB switches on the PWM pins. When PWM rises to HIGH level, LSA or LSB depending on input pin open state again Output current limit and thermal shutdown protection related high side short to ground.

A short to battery condition is latched by an overload detector or thermal shutdown to the associated low side. The active VCC pin voltage clamp protection device targets low energy peak motors in all configurations. The CP pin provides the necessary external N-channel power MOS gate drive for reverse polarity protection.
