VNH5050A-E
Note:
Note:
Series resistor must be inserted to limit the current sunk from the microcontroller I/Os. If
I
Figure 13. Half-bridge configuration
The VNH5050A-E can be used as a high power half-bridge driver.
Figure 14. Multi-motors configuration
The VNH5050A-E can easily be designed in multi-motors driving applications such as seat
positioning systems where only one motor has to be driven at a time. DIAG
to put unused half-bridges in high impedance.
