VNH2SP30-E

Application information

The device sustains no more than -30 A in reverse battery conditions because of the two

body diodes of the power MOSFETs. Additionally, in reverse battery condition the I/Os of the

VNH2SP30-E are pulled down to the VCC line (approximately -1.5 V). A series resistor must

be inserted to limit the current sunk from the microcontroller I/Os. If IRmax is the maximum

target reverse current through µC I/Os, the series resistor is:

Figure 34. Half-bridge configuration

Note:

The VNH2SP30-E can be used as a high power half-bridge driver achieving an On

resistance per leg of 9.5 mΩ.

Figure 35. Multi-motor configuration

Note:

The VNH2SP30-E can easily be designed in multi-motor driving applications such as seat

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

allow the unused half-bridges to be put into high impedance.
