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 14. 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 14. 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.
- Equivalent Device: FULL BRIDGE
- RDS(ON) 0.37 Typ. Value @ TJ = 25°C
- 1.4A max RMS Load Current
- 2.8A max OCD Threshold
