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

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. The input signals IN

and IN

can

directly interface to the microcontroller to select

the motor direction and the brake condition.

The DIAG

/EN

or DIAG

/EN

, when connected

to an external pull-up resistor, enable one leg of

the bridge. They also provide 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 to 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 LS

and LS

switches. When PWM rises to a high-level, LS

turn-on again depending on the input pin

state.

Output current limitation and thermal shutdown

protects the concerned high-side in short to

ground condition.

The short to battery condition is revealed by the

overload detector or by thermal shutdown that

latches off the relevant low-side.

Active V

pin voltage clamp protects the device

against low energy spikes in all configurations for

the motor.

CP pin provides the necessary gate drive for an

external n-channel PowerMOS used for reverse

polarity protection.

Electrical specifications VNH5019A-E Possible origins of fault conditions may be: ● OUTA is shorted to ground. It follows that, high-side A is in overtemperature state. ● OUTA is shorted to VCC. It follow that, low-side Power MOSFET is in saturation state. When a fault condition is detected, the user can know which power element is in fault by monitoring the INA, INB, DIAGA/ENA and DIAGB/ENB pins. In any case, when a fault is detected, the faulty leg of the bridge is latched off.

Electrical specifications 2.5 VNH5019A-E Reverse battery protection Against reverse battery condition the charge pump feature allows to use an external N-channel MOSFET connected as shown in the typical application circuit (see Figure 4). As alternative option, a N-channel MOSFET connected to GND pin can be used (see typical application circuit in figure Figure 5). With this configuration we recommend to short VBAT pin to VCC.
