Note:
When a fault condition is detected, the user can know which power element is in fault by
monitoring the IN
In any case, when a fault is detected, the faulty leg of the bridge is latched off. To turn on the

Reverse battery protection
Three possible solutions can be considered:
a Schottky diode D connected to V
an N-channel MOSFET connected to the GND pin (see
for DC to 20 kHz PWM operation short circuit protection on page
a P-channel MOSFET connected to the V
The device sustains no more than -30A in reverse battery conditions because of the two
body diodes of the power MOSFETs. Additionally, in reverse battery condition the I/Os of
are pulled down to the V
limit the current sunk from the microcontroller I/Os. If I
current through µC I/Os, the series resistor is:

The VNH3ASP30-E can be used as a high power half-bridge driver achieving an On
resistance per leg of 21 mΩ .
