VNH5180A-E

Application information

Doc ID 17074 Rev 5

21/31

Series resistor must be inserted to limit the current sunk from the microcontroller I/Os. If

IRmax is the maximum target reverse current through microcontroller I/Os, series resistor is:

Half-bridge configuration

Note:

The VNH5180A-E can be used as a high power half-bridge driver achieving an On

resistance per leg of 90 m

Ω.

Figure 14.

Multi-motors configuration

Note:

The VNH5180A-E can easily be designed in multi-motors driving applications such as seat

positioning systems where only one motor must be driven at a time. DIAGX/ENX pins allow

to put unused half-bridges in high impedance.
