3.14.2Paralleling the four Half Bridges to get a single Half Bridge
It is also possible to parallel the four Half Bridges to obtain a simple Half Bridge as shown in Figure 27.
This configuration cannot be used with L6207, because of its internal PWM current controllers that work sepa-
rately for bridge A and bridge B. Using this configuration with the L6207 may damage the device.
The resulting half bridge has the following characteristics (typical values).
- Equivalent Device: HALF BRIDGE
- RDS(ON) 0.075
Ω Typ. Value @ TJ = 25°C
- 5.6A max RMS Load Current
- 11.2A OCD Threshold
With L6206 RCLA and RCLB resistors connected to PROGCL pins must have the same value.
