Figure 15.
Parallel connection for higher current
To operate the device in parallel and maintain a lower over current threshold, half bridge 1
and the half bridge 2 of the bridge A can be connected in parallel and the same done for the
bridge B as shown in Figure 16. In this configuration, the peak current for each half bridge is
still limited by the bond wires for the supply and sense pins so the dissipation in the device
will be reduced, but the peak current rating is not increased.
When connected in this configuration the over current detection circuit, senses the sum of
the current in upper devices connected in parallel. With the enables connected in parallel,
an over current will turn of both bridges. Since the circuit senses the total current in the
upper devices, the over current threshold is equal to the threshold set the resistor RCLA or
RCLB in Figure 16. RCLA sets the threshold when outputs OUT1A and OUT2A are high and
resistor RCLB sets the threshold when outputs OUT1B and OUT2B are high.
It is recommended to use RCLA = RCLB.
In this configuration, the resulting bridge has the following characteristics.
